Definitions
- the present disclosure relates generally to the field of corrosion control in a water system, using one or more cationic alkyl polyglycosides.
- the present disclosure relates to using a corrosion control composition comprising one or more cationic alkyl polyglycosides for corrosion control in a water system, especially in a water system for oil and gas operation.
- the methods and corrosion control compositions disclosed herein are effective to prevent corrosion in a water system and more environmentally friendly, since the cationic alkyl polyglycosides can be derived from compounds in natural resources and degraded to natural products.
- a water system including an industrial water system in oil and gas operation, serves many different purposes. Any water system, including its equipment and water, is prone to microbial contamination and fouling. Metal surfaces in any water system are prone to corrosion, partly due to microbial contamination and fouling.
- Corrosion inhibitors are often added into a water system to protect its metal surface infrastructure, such as carbon steel pipelines, from corrosion. Quaternary ammonium compounds have been used for many years as corrosion inhibitors and fouling control agents for a water system.
- Quaternary ammonium compounds belong to an important subcategory of surfactants because they contain unique properties. A main distinction between quaternary ammonium compounds from other surfactants is their unique structures. Quaternary ammonium compounds consist mainly of two moieties, a hydrophobic group, e.g., long alkyl group, and a quaternary ammonium salt group. The unique positive charge of the ammonium plays a key role, e.g., electrostatic interactions, between the surfactant and surface or different components of biofilms.
- the quaternary ammonium compounds used for such purpose are often bis quaternary species or species quaternized with benzyl chloride that are known to be very hazardous.
- governmental regulations exist to release any water containing single quaternary compounds into environment. Therefore, there is a continuing need for different or alternative quaternary ammonium compounds that are better and safer corrosion control agents.
- the exemplary cationic alkyl polyglycoside compounds disclosed herein show their effectiveness for controlling corrosion on a metal surface.
- U.S. Patent Application No. 62/798,193 filed simultaneously herewith and titled “USE OF CATIONIC SUGAR-BASED COMPOUNDS FOR MICROBIAL FOULING CONTROL IN A WATER SYSTEM”, these cationic alkyl polyglycoside compounds were also demonstrated to be effective for preventing bacteria or biofilm growth or as fouling control agent in a fouling control composition for water systems.
- cationic alkyl polyglycosides are preferred because they are derived from natural resources, e.g., polyglycosides and fatty alcohols, and degraded to natural products and are environmentally friendly, but also more effective because they function both as corrosion control agents and microbial/biofilm growth control agents.
- a corrosion control composition wherein the composition comprises a cationic alkyl polyglycoside and one or more additional corrosion control composition agents, wherein the corrosion control composition reduces corrosion on a surface in the water system.
- a method of corrosion control on a surface in a water system comprising providing a corrosion control composition onto a surface in a water system or into a water system to generate a treated water system, wherein the corrosion control composition comprises a cationic alkyl polyglycoside and wherein the corrosion control composition reduces corrosion.
- the corrosion control composition further comprises one or more additional corrosion control composition agents.
- the corrosion control compositions and methods disclosed herein have a surprising advantage of not only preventing corrosion of metal surfaces in a water system but also preventing microbial/biofilm growth, leading to overall reduction in chemical uses, cost, and operation complexity for operating a water system.
- the corrosion control composition or methods disclosed herein are free of other corrosion inhibitor and/or fouling control agent.

- the pH of a use solution of the detergent composition is defined as the pH that is determined at room temperature when the use solution is obtained by diluting the detergent composition with distilled water and contains from 0.5 g/L to about 5 g/L of the composition.
- the concentration of the composition is from about from about 0.5 g/L to about 1 g/L, from about 1 g/L to about 2 g/L, from about 2 g/L to about 3 g/L, from about 3 g/L to about 4 g/L, from about 4 g/L to about 5 g/L, about 0.5 g/L, about 1.0 g/L, about 1.5 g/L, about 2.0 g/L, about 2.5 g/L, about 3.0 g/L, about 3.5 g/L, about 4.0 g/L, about 4.5 g/L, about 5.0 g/L or any value there between in the use solution.
- a use solution of the detergent composition therefore provides a pH of at least about 8, preferably a pH of from about 9.5 to about 12, more preferably from about 10 to about 11 or from about 11 to about 12, when its primary alkalinity source is at a concentration of about 0.1 g/L, about 0.2 g/L, about 0.5 g/L, about 0.8 g/L, or about 1 gram per liter (g/L).

- the pH of the use solution is between about 10 and about 13. In some embodiments, the pH of the use solution is between about 8 and about 10. Particularly, the pH of the use solution is about 11-12. If the pH of the use solution is too low, for example, below approximately 10, the use solution may not provide adequate detergency properties. Further, at lower pH levels, the silicate species become unstable and may precipitate out of solution. If the pH of the use solution is too high, for example, above approximately 13, the use solution may be too alkaline and attack or damage the surface to be cleaned. A further consideration for the pH is that if the composition is too alkaline, a user would be required to wear PPE. However, if the pH of the composition is at or below about 11.5 pH, PPE is not required. Therefore, it is desirable for the pH of the detergent composition disclosed herein in diluted use form to be between about 11 and about 12 for the composition to be effective, but not corrosive to human skin.

- the first class includes acyl/dialkyl ethylenediamine derivatives (e.g. 2-alkyl hydroxyethyl imidazoline derivatives) and their salts.
- the second class includes N-alkylamino acids and their salts.
- Amphoteric surfactants can be synthesized by methods known to those of skill in the art. For example, 2-alkyl hydroxyethyl imidazoline is synthesized by condensation and ring closure of a long chain carboxylic acid (or a derivative) with dialkyl ethylenediamine. Commercial amphoteric surfactants are derivatized by subsequent hydrolysis and ring-opening of the imidazoline ring by alkylation—for example with chloroacetic acid or ethyl acetate. During alkylation, one or two carboxy-alkyl groups react to form a tertiary amine and an ether linkage with differing alkylating agents yielding different tertiary amines.

Alkylation of the primary amino groups of an amino acid leads to secondary and tertiary amines. Alkyl substituents may have additional amino groups that provide more than one reactive nitrogen center. Most commercial N-alkylamine acids are alkyl derivatives of beta-alanine or beta-N(2-carboxyethyl) alanine.

Abstract
Description
- This is a continuation application of U.S. Ser. No. 16/774,226, filed Jan. 28, 2020, which claims priority under 35 U.S.C. § 119 to provisional application Ser. No. 62/798,245, filed Jan. 29, 2019, all of which are herein incorporated by reference in their entirety.
- The present disclosure relates generally to the field of corrosion control in a water system, using one or more cationic alkyl polyglycosides. In particular, the present disclosure relates to using a corrosion control composition comprising one or more cationic alkyl polyglycosides for corrosion control in a water system, especially in a water system for oil and gas operation. The methods and corrosion control compositions disclosed herein are effective to prevent corrosion in a water system and more environmentally friendly, since the cationic alkyl polyglycosides can be derived from compounds in natural resources and degraded to natural products.
- A water system, including an industrial water system in oil and gas operation, serves many different purposes. Any water system, including its equipment and water, is prone to microbial contamination and fouling. Metal surfaces in any water system are prone to corrosion, partly due to microbial contamination and fouling.
- Corrosion inhibitors are often added into a water system to protect its metal surface infrastructure, such as carbon steel pipelines, from corrosion. Quaternary ammonium compounds have been used for many years as corrosion inhibitors and fouling control agents for a water system.
- Quaternary ammonium compounds belong to an important subcategory of surfactants because they contain unique properties. A main distinction between quaternary ammonium compounds from other surfactants is their unique structures. Quaternary ammonium compounds consist mainly of two moieties, a hydrophobic group, e.g., long alkyl group, and a quaternary ammonium salt group. The unique positive charge of the ammonium plays a key role, e.g., electrostatic interactions, between the surfactant and surface or different components of biofilms.
- However, the quaternary ammonium compounds used for such purpose are often bis quaternary species or species quaternized with benzyl chloride that are known to be very hazardous. In additional, governmental regulations exist to release any water containing single quaternary compounds into environment. Therefore, there is a continuing need for different or alternative quaternary ammonium compounds that are better and safer corrosion control agents.
- Accordingly, it is an objective of the present disclosure to develop novel corrosion control agents having improved corrosion control properties.
- It is a further objective of the disclosure to develop methods and corrosion control compositions to make corrosion control in a water system more efficient and effective.
- These and other objects, advantages and features of the present disclosure will become apparent from the following specification taken in conjunction with the claims set forth herein.
- Disclosed herein are the methods and compositions for corrosion control for a metal surface in a water system. Specifically, the disclosed methods and compositions for corrosion control for a metal surface in a water system use one or more water soluble cationic alkyl polyglycoside compounds.
- The exemplary cationic alkyl polyglycoside compounds disclosed herein show their effectiveness for controlling corrosion on a metal surface. In a related application, U.S. Patent Application No. 62/798,193, filed simultaneously herewith and titled “USE OF CATIONIC SUGAR-BASED COMPOUNDS FOR MICROBIAL FOULING CONTROL IN A WATER SYSTEM”, these cationic alkyl polyglycoside compounds were also demonstrated to be effective for preventing bacteria or biofilm growth or as fouling control agent in a fouling control composition for water systems. Not only are these cationic alkyl polyglycosides preferred because they are derived from natural resources, e.g., polyglycosides and fatty alcohols, and degraded to natural products and are environmentally friendly, but also more effective because they function both as corrosion control agents and microbial/biofilm growth control agents.
- In one aspect, provided herein is a corrosion control composition, wherein the composition comprises a cationic alkyl polyglycoside and one or more additional corrosion control composition agents, wherein the corrosion control composition reduces corrosion on a surface in the water system.
- In another aspect, disclosed herein is a method of corrosion control on a surface in a water system, wherein the method comprises providing a corrosion control composition onto a surface in a water system or into a water system to generate a treated water system, wherein the corrosion control composition comprises a cationic alkyl polyglycoside and wherein the corrosion control composition reduces corrosion. In some embodiments, the corrosion control composition further comprises one or more additional corrosion control composition agents.
- The corrosion control compositions and methods disclosed herein have a surprising advantage of not only preventing corrosion of metal surfaces in a water system but also preventing microbial/biofilm growth, leading to overall reduction in chemical uses, cost, and operation complexity for operating a water system. In some embodiments, the corrosion control composition or methods disclosed herein are free of other corrosion inhibitor and/or fouling control agent.

Examples of suitable alkalinity sources include, but are not limited to, sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, sodium silicate, sodium metasilicate, potassium silicate, or a mixture thereof. The alkalinity source is preferably an alkali hydroxide, alkali carbonate, or mixture thereof. The alkalinity source controls the pH of the resulting use solution of the composition disclosed when water or other diluent is added to the composition to form a use solution.
- When the disclosed composition is a detergent composition, the pH of the use solution must be maintained in the alkaline range to provide sufficient detergency properties. Therefore, the disclosed detergent composition comprises more primary alkalinity source than the cationic alkyl polyglycoside or polyglucoside compounds in term of weight percentage.
- A use solution of a composition disclosed herein as used herein refers to a diluted solution for the composition by a diluent. A diluent as used herein refers to water, city water, distilled water, or carrier solvents defined herein. The composition or the compounds can be diluted by a factor of 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11-1,000,000, or any value there between to generate a use solution and then use the use solution for this application. In this disclosure, when a composition disclosed herein is applied, either the composition or use solution thereof is applied.
- When the disclosed composition is a detergent composition, the pH of a use solution of the detergent composition is defined as the pH that is determined at room temperature when the use solution is obtained by diluting the detergent composition with distilled water and contains from 0.1 g/L to about 3 g/L of the primary alkalinity source. In some embodiments, the concentration of the primary alkalinity source is from about 0.1 g/L to about 0.5 g/L, from about 0.5 g/L to about 1 g/L, from about 1 g/L to about 3 g/L, from about 1 g/L to about 2 g/L, from about 2 g/L to about 3 g/L, about 0.1 g/L, about 0.2 g/L, about 0.3 g/L, about 0.4 g/L, about 0.5 g/L, about 1.0 g/L, about 1.5 g/L, about 2.0 g/L, about 2.5 g/L, about 3.0 g/L, or any value there between in the use solution.
- Alternatively, when the disclosed composition is a detergent composition, the pH of a use solution of the detergent composition is defined as the pH that is determined at room temperature when the use solution is obtained by diluting the detergent composition with distilled water and contains from 0.5 g/L to about 5 g/L of the composition. In some embodiments, the concentration of the composition is from about from about 0.5 g/L to about 1 g/L, from about 1 g/L to about 2 g/L, from about 2 g/L to about 3 g/L, from about 3 g/L to about 4 g/L, from about 4 g/L to about 5 g/L, about 0.5 g/L, about 1.0 g/L, about 1.5 g/L, about 2.0 g/L, about 2.5 g/L, about 3.0 g/L, about 3.5 g/L, about 4.0 g/L, about 4.5 g/L, about 5.0 g/L or any value there between in the use solution.
- In some embodiments, a use solution of the detergent composition therefore provides a pH of at least about 8, preferably a pH of from about 9.5 to about 12, more preferably from about 10 to about 11 or from about 11 to about 12, when its primary alkalinity source is at a concentration of about 0.1 g/L, about 0.2 g/L, about 0.5 g/L, about 0.8 g/L, or about 1 gram per liter (g/L). In some embodiments, a use solution of the detergent composition therefore provides a pH of at least 8, preferably a pH of 9.5 to 11, more preferably 10 to 11, from about 11 to about 12, when its primary alkalinity source in distilled water is at a concentration of about 1 g/L, about 1.5 g/L, about 2.0 g/L, about 2.5 g/L, about 3 g/L, or any value there between.
- In some other embodiments, a use solution of the detergent composition therefore provides a pH of at least about 8, preferably a pH of from about 9.5 to about 12, more preferably from about 10 to about 11 or from about 11 to about 12, when the composition itself is at a concentration of about 0.5 g/L, about 0.8 g/L, about 1 g/L, about 1.5 g/L, about 2.0 g/L, about 2.5 g/L, about 3.0 g/L, about 3.5 g/L, about 4.0 g/L, about 4.5 g/L, or about 5.0 g/L. In some embodiments, a use solution of the detergent composition therefore provides a pH of at least 8, preferably a pH of 9.5 to 11, more preferably 10 to 11, from about 11 to about 12, when the composition itself is at a concentration of about 1 g/L, about 1.5 g/L, about 2.0 g/L, about 2.5 g/L, about 3 g/L, about 3.5 g/L, about 4.0, g/L, about 4.5 g/L, about 5.0 g/L, or any value there between.
- In some embodiments, the pH of the use solution is between about 10 and about 13. In some embodiments, the pH of the use solution is between about 8 and about 10. Particularly, the pH of the use solution is about 11-12. If the pH of the use solution is too low, for example, below approximately 10, the use solution may not provide adequate detergency properties. Further, at lower pH levels, the silicate species become unstable and may precipitate out of solution. If the pH of the use solution is too high, for example, above approximately 13, the use solution may be too alkaline and attack or damage the surface to be cleaned. A further consideration for the pH is that if the composition is too alkaline, a user would be required to wear PPE. However, if the pH of the composition is at or below about 11.5 pH, PPE is not required. Therefore, it is desirable for the pH of the detergent composition disclosed herein in diluted use form to be between about 11 and about 12 for the composition to be effective, but not corrosive to human skin.
- Preferably, the primary alkalinity source is an alkali metal hydroxide. Preferred alkali metal hydroxides include sodium hydroxide and potassium hydroxide. More preferably, the primary alkalinity source is sodium hydroxide. Sodium carbonate can be of light density or heavy density.
- When a carbonate is included in the disclosed detergent composition, an effective amount of the alkali metal carbonate is an amount that provides a use solution having a pH of at least 8, preferably a pH of 9.5 to 11, more preferably 10 to 10.3.
- In general, when the primary alkalinity source is present in the disclosed detergent composition at a concentration of at least about 1 wt-%, the composition or a use solution of the composition can emulsify fats and oils present. When the primary alkalinity source is present in a concentration of about 3 wt-% or greater, the composition or a use solution of the composition can emulsify, suspend, and separate oils and fats after treatment.
- In some embodiments where the disclosed composition is not a detergent composition, the composition is free of a primary alkalinity source.
- The detergent compositions disclosed herein include one or more builders. In some embodiments, a builder may also serve as a part of the primary alkalinity source in the detergent compositions. In some embodiments, the builder includes a carbonate, hydroxide, metasilicate, or mixture thereof. In some embodiments, a carbonate can assist in providing solid detergent compositions, as the carbonate can act as a hydratable salt.

- In some embodiments, the composition disclosed herein is free of a scale inhibitor.
- The compositions or detergent compositions disclosed herein can include an enzyme. An enzyme in the detergent compositions enhances removal of soils, prevents redeposition, and/or reduces foam during applications of the detergent compositions or their use solutions. The function of an enzyme is to break down adherent soils, such as starch or proteinaceous materials, typically found in soiled surfaces and removed by a detergent composition into a wash water source.
- Exemplary types of enzymes which can be incorporated into the detergent compositions disclosed herein include, but are not limited to, amylase, protease, lipase, cellulase, cutinase, gluconase, peroxidase, and/or mixtures thereof. A composition disclosed herein may employ more than one enzyme, from any suitable origin, such as vegetable, animal, bacterial, fungal or yeast origin. In some embodiments, the enzyme is a protease. As used herein, the terms “protease” or “proteinase” refer enzymes that catalyze the hydrolysis of peptide bonds.
- As one skilled in the art shall ascertain, enzymes are designed to work with specific types of soils. For example, according to an embodiment of the invention, ware wash applications may use a protease enzyme as it is effective at the high temperatures of the ware wash machines and is effective in reducing protein-based soils. Protease enzymes are particularly advantageous for cleaning soils containing protein, such as blood, cutaneous scales, mucus, grass, food (e.g., egg, milk, spinach, meat residue, tomato sauce), or the like. Protease enzymes are capable of cleaving macromolecular protein links of amino acid residues and convert substrates into small fragments that are readily dissolved or dispersed into the aqueous use solution. Proteases are often referred to as detersive enzymes due to the ability to break soils through the chemical reaction known as hydrolysis. Protease enzymes can be obtained, for example, from Bacillus subtilis, Bacillus licheniformis and Streptomyces griseus. Protease enzymes are also commercially available as serine endoproteases.
- Examples of commercially-available protease enzymes are available under the following trade names: Esperase, Purafect, Purafect L, Purafect Ox, Everlase, Liquanase, Savinase, Prime L, Prosperase and Blap.
- The enzyme to be included into the detergent composition may be an independent entity and/or may be formulated in combination with the detergent composition. In some embodiments, the enzyme may be formulated into a detergent composition in either liquid or solid formulations. In addition, enzyme compositions may be formulated into various delayed or controlled release formulations. For example, a solid molded detergent composition may be prepared without the addition of heat. As a skilled artisan will appreciate, enzymes tend to become denatured by the application of heat and therefore use of enzymes within detergent compositions require methods of forming detergent compositions that does not rely upon heat as a step in the formation process, such as solidification.
- The enzyme composition may further be obtained commercially in a solid (e.g., puck, powder, etc.) or liquid formulation. Commercially-available enzymes are generally combined with stabilizers, buffers, cofactors and inert vehicles. The actual active enzyme content depends upon the method of manufacture, which is well known to a skilled artisan and such methods of manufacture are not critical to the present invention.
- Alternatively, the enzyme composition may be provided separate from the detergent composition, such as added directly to a use solution of a detergent composition or a wash liquor, or wash water of an application, e.g. dishwasher.

Exemplary additional detergent composition agents include, but are not limited to, a threshold agent; crystal modifier; hardening agent; bleaching agent; peroxycarboxylic acid, peroxycarboxylic acid composition, filler; defoaming agent; anti-redeposition agent; stabilizing agent; dispersant; fragrance and dye; and thickener.
- In some embodiments, the detergent composition disclosed herein is free of one, more, or all the additional detergent composition agents.
- Anionic surfactants are surface active substances in which the charge on the hydrophobe is negative; or surfactants in which the hydrophobic section of the molecule carries no charge unless the pH is elevated to neutrality or above (e.g., carboxylic acids). Carboxylate, sulfonate, sulfate and phosphate are the polar (hydrophilic) solubilizing groups found in anionic surfactants. Of the cations (counter ions) associated with these polar groups, sodium, lithium and potassium impart water solubility; ammonium and substituted ammonium ions provide both water and oil solubility; and, calcium, barium, and magnesium promote oil solubility. As those skilled in the art understand, anionic surfactants are excellent detersive surfactants and are therefore favored additions to heavy duty detergent compositions.

Such carboxylates include alkyl ethoxy carboxylates, alkyl aryl ethoxy carboxylates, alkyl polyethoxy polycarboxylate surfactants and soaps (e.g., alkyl carboxyls). Secondary carboxylates useful in the present compositions include those which contain a carboxyl unit connected to a secondary carbon. The secondary carbon can be in a ring structure, e.g., as in p-octyl benzoic acid, or as in alkyl-substituted cyclohexyl carboxylates. The secondary carboxylate surfactants typically contain no ether linkages, no ester linkages and no hydroxyl groups. Further, they typically lack nitrogen atoms in the group-group (amphiphilic portion). Suitable secondary soap surfactants typically contain 11-13 total carbon atoms, although more carbons atoms (e.g., up to 16) can be present. Suitable carboxylates also include acylamino acids (and salts), such as acylgluamates, acyl peptides, sarcosinates (e.g., N-acyl sarcosinates), taurates (e.g., N-acyl taurates and fatty acid amides of methyl tauride), and the like.

- In some embodiments, the composition or detergent composition disclosed herein is free of an anionic surfactant.
- Useful nonionic surfactants are generally characterized by the presence of an organic hydrophobic group and an organic hydrophilic group and are typically produced by the condensation of an organic aliphatic, alkyl aromatic or polyoxyalkylene hydrophobic compound with a hydrophilic alkaline oxide moiety which in common practice is ethylene oxide or a polyhydration product thereof, polyethylene glycol. Practically any hydrophobic compound having a hydroxyl, carboxyl, amino, or amido group with a reactive hydrogen atom can be condensed with ethylene oxide, or its polyhydration adducts, or its mixtures with alkoxylenes such as propylene oxide to form a nonionic surface-active agent. The length of the hydrophilic polyoxyalkylene moiety which is condensed with any particular hydrophobic compound can be readily adjusted to yield a water dispersible or water-soluble compound having the desired degree of balance between hydrophilic and hydrophobic properties. Useful nonionic surfactants include:
- Block polyoxypropylene-polyoxyethylene polymeric compounds based upon propylene glycol, ethylene glycol, glycerol, trimethylolpropane, and ethylenediamine as the initiator reactive hydrogen compound. Examples of polymeric compounds made from a sequential propoxylation and ethoxylation of initiator are commercially available from BASF Corp. One class of compounds are difunctional (two reactive hydrogens) compounds formed by condensing ethylene oxide with a hydrophobic base formed by the addition of propylene oxide to the two hydroxyl groups of propylene glycol. This hydrophobic portion of the molecule weighs from about 1,000 to about 4,000. Ethylene oxide is then added to sandwich this hydrophobe between hydrophilic groups, controlled by length to constitute from about 10% by weight to about 80% by weight of the final molecule. Another class of compounds are tetra-flinctional block copolymers derived from the sequential addition of propylene oxide and ethylene oxide to ethylenediamine. The molecular weight of the propylene oxide hydrotype ranges from about 500 to about 7,000; and, the hydrophile, ethylene oxide, is added to constitute from about 10% by weight to about 80% by weight of the molecule.
- Condensation products of one mole of alkyl phenol wherein the alkyl chain, of straight chain or branched chain configuration, or of single or dual alkyl constituent, contains from about 8 to about 18 carbon atoms with from about 3 to about 50 moles of ethylene oxide. The alkyl group can, for example, be represented by diisobutylene, di-amyl, polymerized propylene, iso-octyl, nonyl, and di-nonyl. These surfactants can be polyethylene, polypropylene, and polybutylene oxide condensates of alkyl phenols.

Examples of like commercial surfactant are available under the trade names Lutensol™, Dehydol™ manufactured by BASF, Neodol™ manufactured by Shell Chemical Co. and Alfonic™ manufactured by Vista Chemical Co.
- Condensation products of one mole of saturated or unsaturated, straight or branched chain carboxylic acid having from about 8 to about 18 carbon atoms with from about 6 to about 50 moles of ethylene oxide.

Examples of commercial compounds of this chemistry are available on the market under the trade names Disponil or Agnique manufactured by BASF and Lipopeg™ manufactured by Lipo Chemicals, Inc.
- In addition to ethoxylated carboxylic acids, commonly called polyethylene glycol esters, other alkanoic acid esters formed by reaction with glycerides, glycerin, and polyhydric (saccharide or sorbitan/sorbitol) alcohols have application in this invention for specialized embodiments, particularly indirect food additive applications. All of these ester moieties have one or more reactive hydrogen sites on their molecule which can undergo further acylation or ethylene oxide (alkoxide) addition to control the hydrophilicity of these substances. Care must be exercised when adding these fatty esters or acylated carbohydrates to compositions of the present invention containing amylase and/or lipase enzymes because of potential incompatibility.
- Examples of nonionic low foaming surfactants include, but are not limited to, compounds which are modified, essentially reversed, by adding ethylene oxide to ethylene glycol to provide a hydrophile of designated molecular weight; and, then adding propylene oxide to obtain hydrophobic blocks on the outside (ends) of the molecule. The hydrophobic portion of the molecule weighs from about 1,000 to about 3,100 with the central hydrophile including 10% by weight to about 80% by weight of the final molecule. These reverse Pluronics™ are manufactured by BASF Corporation under the trade name Pluronic™ R surfactants. Likewise, the Tetronic™ R surfactants are produced by BASF Corporation by the sequential addition of ethylene oxide and propylene oxide to ethylenediamine. The hydrophobic portion of the molecule weighs from about 2,100 to about 6,700 with the central hydrophile including 10% by weight to 80% by weight of the final molecule.
- Compounds which are modified by “capping” or “end blocking” the terminal hydroxy group or groups (of multi-functional moieties) to reduce foaming by reaction with a small hydrophobic molecule such as propylene oxide, butylene oxide, benzyl chloride; and, short chain fatty acids, alcohols or alkyl halides containing from 1 to about 5 carbon atoms; and mixtures thereof. Also included are reactants such as thionyl chloride which convert terminal hydroxy groups to a chloride group. Such modifications to the terminal hydroxy group may lead to all-block, block-heteric, heteric-block or all-heteric nonionics.

Other variations on the scope of these compounds may be represented by the alternative formula: R20—(PO)V—N[(EO)wH][(EO)zH] in which R20 is as defined above, v is 1 to 20 (e.g., 1, 2, 3, or 4 (preferably 2)), and w and z are independently 1-10, preferably 2-5. These compounds are represented commercially by a line of products sold by Huntsman Chemicals as nonionic surfactants. A preferred chemical of this class includes Surfonic™ PEA 25 Amine Alkoxylate. Preferred nonionic surfactants for the compositions of the invention include alcohol alkoxylates, EO/PO block copolymers, alkylphenol alkoxylates, and the like.
- The treatise Nonionic Surfactants, edited by Schick, M. J., Vol. 1 of the Surfactant Science Series, Marcel Dekker, Inc., New York, 1983 is an excellent reference on the wide variety of nonionic compounds generally employed in the practice of the present invention. A typical listing of nonionic classes, and species of these surfactants, is given in U.S. Pat. No. 3,929,678 issued to Laughlin and Heuring on Dec. 30, 1975. Further examples are given in “Surface Active Agents and detergents” (Vol. I and II by Schwartz, Perry and Berch).
- Suitable nonionic surfactants suitable for use with the compositions of the present invention include alkoxylated surfactants. Suitable alkoxylated surfactants include EO/PO copolymers, fully capped or partially EO/PO copolymers, alcohol alkoxylates, capped alcohol alkoxylates, mixtures thereof, or the like. Suitable alkoxylated surfactants for use as solvents include EO/PO block copolymers, such as the Pluronic and reverse Pluronic surfactants; alcohol alkoxylates, such as Dehypon LS-54 (R-(EO)5(PO)4) and Dehypon LS-36 (R-(EO)3(PO)6); and capped alcohol alkoxylates, such as Plurafac LF221 and Tegoten EC11; mixtures thereof, or the like.
- In some embodiments that are not detergent compositions, the composition disclosed herein is free of a nonionic surfactant.
- The semi-polar type of nonionic surfactants are another class of nonionic surfactants useful in compositions disclosed herein. Generally, semi-polar nonionic surfactants are high foaming agents and foam stabilizers, which can limit their application in CIP systems. However, in some embodiments designed for high foaming composition or detergent composition, semi-polar nonionic surfactants would have immediate utility. The semi-polar nonionic surfactants include, but are not limited to, the amine oxides, phosphine oxides, sulfoxides and their alkoxylated derivatives.
- Amine oxides are tertiary amine oxides corresponding to the general formula:
- wherein the arrow is a conventional representation of a semi-polar bond; and, R1, R2, and R3 may be aliphatic, aromatic, heterocyclic, alicyclic, or combinations thereof. Generally, for amine oxides of detergent interest, R1 is an alkyl radical of from about 8 to about 24 carbon atoms; R2 and R3 are alkyl or hydroxyalkyl of 1-3 carbon atoms or a mixture thereof; R2 and R3 can be attached to each other, e.g. through an oxygen or nitrogen atom, to form a ring structure; R4 is an alkylene or a hydroxyalkylene group containing 2 to 3 carbon atoms; and n ranges from 0 to about 20.
- Useful water soluble amine oxide surfactants are selected from the coconut or tallow alkyl di-(lower alkyl) amine oxides, specific examples of which are dodecyldimethylamine oxide, tridecyldimethylamine oxide, etradecyldimethylamine oxide, pentadecyldimethylamine oxide, hexadecyldimethylamine oxide, heptadecyldimethylamine oxide, octadecyldimethylaine oxide, dodecyldipropylamine oxide, tetradecyldipropylamine oxide, hexadecyldipropylamine oxide, tetradecyldibutylamine oxide, octadecyldibutylamine oxide, bis(2-hydroxyethyl)dodecylamine oxide, bis(2-hydroxyethyl)-3-dodecoxy-1-hydroxypropylamine oxide, dimethyl-(2-hydroxydodecyl)amine oxide, 3,6,9-trioctadecyldimethylamine oxide and 3-dodecoxy-2-hydroxypropyldi-(2-hydroxyethyl)amine oxide.
- Useful semi-polar nonionic surfactants also include the water-soluble phosphine oxides having the following structure:
- wherein the arrow is a conventional representation of a semi-polar bond; and, R1 is an alkyl, alkenyl or hydroxyalkyl moiety ranging from 10 to about 24 carbon atoms in chain length; and, R2 and R3 are each alkyl moieties separately selected from alkyl or hydroxyalkyl groups containing 1 to 3 carbon atoms.
- Examples of useful phosphine oxides include dimethyldecylphosphine oxide, dimethyltetradecylphosphine oxide, methylethyltetradecylphosphone oxide, dimethylhexadecylphosphine oxide, diethyl-2-hydroxyoctyldecylphosphine oxide, bis(2-hydroxyethyl)dodecylphosphine oxide, and bis(hydroxymethyl)tetradecylphosphine oxide.
- Semi-polar nonionic surfactants useful herein also include the water soluble sulfoxide compounds which have the structure:
- wherein the arrow is a conventional representation of a semi-polar bond; and, R1 is an alkyl or hydroxyalkyl moiety of about 8 to about 28 carbon atoms, from 0 to about 5 ether linkages and from 0 to about 2 hydroxyl substituents; and R2 is an alkyl moiety consisting of alkyl and hydroxyalkyl groups having 1 to 3 carbon atoms.
- Useful examples of these sulfoxides include dodecyl methyl sulfoxide; 3-hydroxy tridecyl methyl sulfoxide; 3-methoxy tridecyl methyl sulfoxide; and 3-hydroxy-4-dodecoxybutyl methyl sulfoxide.
- Semi-polar nonionic surfactants for the compositions of the invention include dimethyl amine oxides, such as lauryl dimethyl amine oxide, myristyl dimethyl amine oxide, cetyl dimethyl amine oxide, combinations thereof, and the like. Useful water soluble amine oxide surfactants are selected from the octyl, decyl, dodecyl, isododecyl, coconut, or tallow alkyl di-(lower alkyl) amine oxides, specific examples of which are octyldimethylamine oxide, nonyldimethylamine oxide, decyldimethylamine oxide, undecyldimethylamine oxide, dodecyldimethylamine oxide, iso-dodecyldimethyl amine oxide, tridecyldimethylamine oxide, tetradecyldimethylamine oxide, pentadecyldimethylamine oxide, hexadecyldimethylamine oxide, heptadecyldimethylamine oxide, octadecyldimethylaine oxide, dodecyldipropylamine oxide, tetradecyldipropylamine oxide, hexadecyldipropylamine oxide, tetradecyldibutylamine oxide, octadecyldibutylamine oxide, bis(2-hydroxyethyl)dodecylamine oxide, bis(2-hydroxyethyl)-3-dodecoxy-1-hydroxypropylamine oxide, dimethyl-(2-hydroxydodecyl)amine oxide, 3,6,9-trioctadecyldimethylamine oxide and 3-dodecoxy-2-hydroxypropyldi-(2-hydroxyethyl)amine oxide.
- In some embodiments, the composition or detergent composition disclosed herein is free of a semi-polar nonionic surfactant.
- Surface active substances are classified as cationic if the charge on the hydrotrope portion of the molecule is positive. Surfactants in which the hydrotrope carries no charge unless the pH is lowered close to neutrality or lower, but which are then cationic (e.g. alkyl amines), are also included in this group. In theory, cationic surfactants may be synthesized from any combination of elements containing an “onium” structure RnX+Y— and could include compounds other than nitrogen (ammonium) such as phosphorus (phosphonium) and sulfur (sulfonium). In practice, the cationic surfactant field is dominated by nitrogen containing compounds, probably because synthetic routes to nitrogenous cationics are simple and straightforward and give high yields of product, which can make them less expensive.
- Cationic surfactants preferably include, more preferably refer to, compounds containing at least one long carbon chain hydrophobic group and at least one positively charged nitrogen. The long carbon chain group may be attached directly to the nitrogen atom by simple substitution; or more preferably indirectly by a bridging functional group or groups in so-called interrupted alkylamines and amido amines. Such functional groups can make the molecule more hydrophilic and/or more water dispersible, more easily water solubilized by co-surfactant mixtures, and/or water soluble. For increased water solubility, additional primary, secondary or tertiary amino groups can be introduced, or the amino nitrogen can be quaternized with low molecular weight alkyl groups. Further, the nitrogen can be a part of branched or straight chain moiety of varying degrees of unsaturation or of a saturated or unsaturated heterocyclic ring. In addition, cationic surfactants may contain complex linkages having more than one cationic nitrogen atom.
- The surfactant compounds classified as amine oxides, amphoterics and zwitterions are themselves typically cationic in near neutral to acidic pH solutions and can overlap surfactant classifications. Polyoxyethylated cationic surfactants generally behave like nonionic surfactants in alkaline solution and like cationic surfactants in acidic solution.
- The simplest cationic amines, amine salts and quaternary ammonium compounds can be schematically drawn thus:
- in which, R represents an alkyl chain, R′, R″, and R′ may be either alkyl chains or aryl groups or hydrogen and X represents an anion. The amine salts and quaternary ammonium compounds are preferred for practical use in this invention due to their high degree of water solubility.
- Most large volume commercial cationic surfactants can be subdivided into four major classes and additional sub-groups known to those skilled in the art and described in “Surfactant Encyclopedia”, Cosmetics & Toiletries, Vol. 104 (2) 86-96 (1989). The first class includes alkylamines and their salts. The second class includes alkyl imidazolines. The third class includes ethoxylated amines. The fourth class includes quaternaries, such as alkylbenzyldimethylammonium salts, alkyl benzene salts, heterocyclic ammonium salts, tetra alkylammonium salts, and the like. Cationic surfactants are known to have a variety of properties that can be beneficial in the present compositions. These desirable properties can include detergency in compositions of or below neutral pH, antimicrobial efficacy, thickening or gelling in cooperation with other agents, and the like.
- Cationic surfactants useful in the compositions disclosed herein include those having the formula R1 mR2 xYLZ wherein each R1 is an organic group containing a straight or branched alkyl or alkenyl group optionally substituted with up to three phenyl or hydroxy groups and optionally interrupted by up to four of the following structures:
- or an isomer or mixture of these structures, and which contains from about 8 to 22 carbon atoms. The R1 groups can additionally contain up to 12 ethoxy groups. m is a number from 1 to 3. Preferably, no more than one R1 group in a molecule has 16 or more carbon atoms when m is 2 or more than 12 carbon atoms when m is 3. Each R2 is an alkyl or hydroxyalkyl group containing from 1 to 4 carbon atoms or a benzyl group with no more than one R2 in a molecule being benzyl, and x is a number from 0 to 11, preferably from 0 to 6. The remainder of any carbon atom positions on the Y group are filled by hydrogens.
- Y is can be a group including, but not limited to:
- or a mixture thereof. Preferably, L is 1 or 2, with the Y groups being separated by a moiety selected from R1 and R2 analogs (preferably alkylene or alkenylene) having from 1 to about 22 carbon atoms and two free carbon single bonds when L is 2. Z is a water-soluble anion, such as a halide, sulfate, methylsulfate, hydroxide, or nitrate anion, particularly preferred being chloride, bromide, iodide, sulfate or methyl sulfate anions, in a number to give electrical neutrality of the cationic component.
- In some embodiments, the composition or detergent composition disclosed herein is free of a cationic surfactant.
- Amphoteric, or ampholytic, surfactants contain both a basic and an acidic hydrophilic group and an organic hydrophobic group. These ionic entities may be any of anionic or cationic groups described herein for other types of surfactants. A basic nitrogen and an acidic carboxylate group are the typical functional groups employed as the basic and acidic hydrophilic groups. In a few surfactants, sulfonate, sulfate, phosphonate or phosphate provide the negative charge.
- Amphoteric surfactants can be broadly described as derivatives of aliphatic secondary and tertiary amines, in which the aliphatic radical may be straight chain or branched and wherein one of the aliphatic substituents contains from about 8 to 18 carbon atoms and one contains an anionic water solubilizing group, e.g., carboxy, sulfo, sulfato, phosphato, or phosphono. Amphoteric surfactants are subdivided into two major classes known to those of skill in the art and described in “Surfactant Encyclopedia” Cosmetics & Toiletries, Vol. 104 (2) 69-71 (1989), which is herein incorporated by reference in its entirety. The first class includes acyl/dialkyl ethylenediamine derivatives (e.g. 2-alkyl hydroxyethyl imidazoline derivatives) and their salts. The second class includes N-alkylamino acids and their salts. Some amphoteric surfactants can be envisioned as fitting into both classes.
- Amphoteric surfactants can be synthesized by methods known to those of skill in the art. For example, 2-alkyl hydroxyethyl imidazoline is synthesized by condensation and ring closure of a long chain carboxylic acid (or a derivative) with dialkyl ethylenediamine. Commercial amphoteric surfactants are derivatized by subsequent hydrolysis and ring-opening of the imidazoline ring by alkylation—for example with chloroacetic acid or ethyl acetate. During alkylation, one or two carboxy-alkyl groups react to form a tertiary amine and an ether linkage with differing alkylating agents yielding different tertiary amines.
- Long chain imidazole derivatives having application in the present invention generally have the general formula:
-
- wherein R is an acyclic hydrophobic group containing from about 8 to 18 carbon atoms and M is a cation to neutralize the charge of the anion, generally sodium. Commercially prominent imidazoline-derived amphoterics that can be employed in the present compositions include for example: Cocoamphopropionate, Cocoamphocarboxy-propionate, Cocoamphoglycinate, Cocoamphocarboxy-glycinate, Cocoamphopropyl-sulfonate, and Cocoamphocarboxy-propionic acid. Amphocarboxylic acids can be produced from fatty imidazolines in which the dicarboxylic acid functionality of the amphodicarboxylic acid is diacetic acid and/or dipropionic acid.
- The carboxymethylated compounds (glycinates) described herein above frequently are called betaines. Betaines are a special class of amphoteric discussed herein below in the section entitled, Zwitterion Surfactants.
- Long chain N-alkylamino acids are readily prepared by reaction RNH2, in which R═C8-C18 straight or branched chain alkyl, fatty amines with halogenated carboxylic acids. Alkylation of the primary amino groups of an amino acid leads to secondary and tertiary amines. Alkyl substituents may have additional amino groups that provide more than one reactive nitrogen center. Most commercial N-alkylamine acids are alkyl derivatives of beta-alanine or beta-N(2-carboxyethyl) alanine. Examples of commercial N-alkylamino acid ampholytes having application in this invention include alkyl beta-amino dipropionates, RN(C2H4COOM)2 and RNHC2H4COOM. In an embodiment, R can be an acyclic hydrophobic group containing from about 8 to about 18 carbon atoms, and M is a cation to neutralize the charge of the anion.
- Suitable amphoteric surfactants include those derived from coconut products such as coconut oil or coconut fatty acid. Additional suitable coconut derived surfactants include as part of their structure an ethylenediamine moiety, an alkanolamide moiety, an amino acid moiety, e.g., glycine, or a combination thereof; and an aliphatic substituent of from about 8 to 18 (e.g., 12) carbon atoms. Such a surfactant can also be considered an alkyl amphodicarboxylic acid. These amphoteric surfactants can include chemical structures represented as: C12-alkyl-C(O)—NH—CH2—CH2—N+(CH2—CH2—CO2Na)2—CH2—CH2—OH or C12-alkyl-C(O)—N(H)—CH2—CH2—N+(CH2—CO2Na)2—CH2—CH2-0H. Disodium cocoampho dipropionate is one suitable amphoteric surfactant and is commercially available under the tradename Miranol™ FBS from Rhodia Inc., Cranbury, N.J. Another suitable coconut derived amphoteric surfactant with the chemical name disodium cocoampho diacetate is sold under the tradename Mirataine™ JCHA, also from Rhodia Inc., Cranbury, N.J.
- A typical listing of amphoteric classes, and species of these surfactants, is given in U.S. Pat. No. 3,929,678 issued to Laughlin and Heuring on Dec. 30, 1975. Further examples are given in “Surface Active Agents and Detergents” (Vol. I and II by Schwartz, Perry and Berch). Each of these references are herein incorporated by reference in their entirety.
- In some embodiments, the composition or detergent composition disclosed herein is free of an amphoteric surfactant.
- Zwitterionic surfactants can be thought of as a subset of the amphoteric surfactants and can include an anionic charge. Zwitterionic surfactants can be broadly described as derivatives of secondary and tertiary amines, derivatives of heterocyclic secondary and tertiary amines, or derivatives of quaternary ammonium, quaternary phosphonium or tertiary sulfonium compounds. Typically, a zwitterionic surfactant includes a positive charged quaternary ammonium or, in some cases, a sulfonium or phosphonium ion; a negative charged carboxyl group; and an alkyl group. Zwitterionic surfactants generally contain cationic and anionic groups which ionize to a nearly equal degree in the isoelectric region of the molecule and which can develop strong“inner-salt” attraction between positive-negative charge centers. Examples of such zwitterionic synthetic surfactants include derivatives of aliphatic quaternary ammonium, phosphonium, and sulfonium compounds, in which the aliphatic radicals can be straight chain or branched, and wherein one of the aliphatic substituents contains from 8 to 18 carbon atoms and one contains an anionic water solubilizing group, e.g., carboxy, sulfonate, sulfate, phosphate, or phosphonate.
- Betaine and sultaine surfactants are exemplary zwitterionic surfactants for use herein. A general formula for these compounds is:
- wherein R1 contains an alkyl, alkenyl, or hydroxyalkyl radical of from 8 to 18 carbon atoms having from 0 to 10 ethylene oxide moieties and from 0 to 1 glyceryl moiety; Y is selected from the group consisting of nitrogen, phosphorus, and sulfur atoms; R2 is an alkyl or monohydroxy alkyl group containing 1 to 3 carbon atoms; x is 1 when Y is a sulfur atom and 2 when Y is a nitrogen or phosphorus atom, R3 is an alkylene or hydroxy alkylene or hydroxy alkylene of from 1 to 4 carbon atoms and Z is a radical selected from the group consisting of carboxylate, sulfonate, sulfate, phosphonate, and phosphate groups.
- Examples of zwitterionic surfactants having the structures listed above include: 4-[N,N-di(2-hydroxyethyl)-N-octadecylammonio]-butane-1-carboxylate; 5-[S-3-hydroxypropyl-S-hexadecylsulfonio]-3-hydroxypentane-1-sulfate; 3-[P,P-diethyl-P-3,6,9-trioxatetracosanephosphonio]-2-hydroxypropane-1-phosphate; 3-[N,N-dipropyl-N-3-dodecoxy-2-hydroxypropyl-ammonio]-propane-1-phosphonate; 3-(N,N-dimethyl-N-hexadecylammonio)-propane-1-sulfonate; 3-(N,N-dimethyl-N-hexadecylammonio)-2-hydroxy-propane-1-sulfonate; 4-[N,N-di(2(2-hydroxyethyl)-N(2-hydroxydodecyl)ammonio]-butane-1-carboxylate; 3-[S-ethyl-S-(3-dodecoxy-2-hydroxypropyl)sulfonio]-propane-1-phosphate; 3-[P,P-dimethyl-P-dodecylphosphonio]-propane-1-phosphonate; and S[N,N-di(3-hydroxypropyl)-N-hexadecylammonio]-2-hydroxy-pentane-1-sulfate. The alkyl groups contained in said detergent surfactants can be straight or branched and saturated or unsaturated.
- The zwitterionic surfactant suitable for use in the present compositions includes a betaine of the general structure:
- These surfactant betaines typically do not exhibit strong cationic or anionic characters at pH extremes nor do they show reduced water solubility in their isoelectric range. Unlike “external” quaternary ammonium salts, betaines are compatible with anionics. Examples of suitable betaines include coconut acylamidopropyldimethyl betaine; hexadecyl dimethyl betaine; C12-14 acylamidopropylbetaine; C8-14 acylamidohexyldiethyl betaine; 4-C14-16 acylmethylamidodiethylammonio-1-carboxybutane; C16-18 acylamidodimethylbetaine; C12-16 acylamidopentanediethylbetaine; and C12-16 acylmethylamidodimethylbetaine.
- Sultaines useful in the present invention include those compounds having the formula (R(R1)2 R2SO3−, in which R is a C6-C18 hydrocarbyl group, each R1 is typically independently C1-C3 alkyl, e.g., methyl, and R2 is a C1-C6 hydrocarbyl group, e.g., a C1-C3 alkylene or hydroxyalkylene group.
- A typical listing of zwitterionic classes, and species of these surfactants, is given in U.S. Pat. No. 3,929,678 issued to Laughlin and Heuring on Dec. 30, 1975. Further examples are given in “Surface Active Agents and Detergents” (Vol. I and II by Schwartz, Perry and Berch). Each of these references are herein incorporated in their entirety.
- In some embodiments, the composition or detergent composition disclosed herein is free of a zwitterionic surfactant.
- While conventional surfactants generally have one hydrophilic group and one hydrophobic group, a Gemini surfactant has at least two hydrophobic groups and at least two hydrophilic groups. These surfactants have the general formula: A1-G-A2 and get their name because they comprise two surfactant moieties (A1, A2) joined by a spacer (G), wherein each surfactant moiety (A1, A2) has a hydrophilic group and a hydrophobic group. Generally, the two surfactant moieties (A1, A2) are the same, but they can be different.
- The Gemini surfactants may be anionic, nonionic, cationic or amphoteric. The hydrophilic and hydrophobic groups of each surfactant moiety (A1, A2) may be any of those known to be used in conventional surfactants having one hydrophilic group and one hydrophobic group. For example, a typical nonionic Gemini surfactant, e.g., a bis-polyoxyethylene alkyl ether, would contain two polyoxyethylene alkyl ether moieties. Each moiety would contain a hydrophilic group, e.g., polyethylene oxide, and a hydrophobic group, e.g., an alkyl chain.
- Anionic and nonionic Gemini surfactants include those of the formula:

- Z is independently hydrogen, —SO3Y, —P(O)(OY)2, —COOY, —CH2COOY, —CH2CH(OH)CH2SO3Y and when R32 is not a polyether, Z is also —OSO3Y, and —OP(O)(OY)2; wherein Y is hydrogen, alkali metal such as sodium and potassium; alkaline earth metal such as magnesium and calcium: ammonium: or organic base salt such as monoethanolamine, diethanolamine, triethanolamine, triethylamine, trimethylamine, N-hydroxyethyl morpholine, and the like.
- A1 or A2 is independently a straight chain or branched C1 to C6 alkyl, an O—R5—O— group or aryl: preferably phenyl; R33 is a bond, an aryl group such as a phenyl or diphenyl group, a C1 to C10 alkyl group, preferably a C1 to C4 alkyl group, most preferably methylene, —C≡C—, —O—, —S—, —S—S—, —N(R36)—, —R35O—, —R35O(EO)a(PO)b—, -D1-R38-D1- or —R3-D1-R38—, wherein R38 is independently a C1-C10 alkyl group, —C(O)—, —R3“O(EO)a(PO)b—, —O—R”—O—, or aryl, e.g. phenyl, and D1 is independently —O—, —S—, —S—S—, —SO2—, —C(O)—, a polyether group —O(EO)a(PO)b—, an amide group —C(O)N(R3)—, an amino group —N(R36)—, —O—R5—O—, or aryl wherein R35, R36, a and b are as defined above.
- On the formulae of this disclosure, the term “alkali” includes substituted alkali, especially the hydroxy substituted derivatives thereof and straight as well as branched chains. When Z is hydrogen, the gemini surfactants are nonionic.
- Other Gemini surfactants specifically useful in the present disclosure include gemini anionic or nonionic surfactants of the formulae:
- wherein Rc represents aryl, preferably phenyl. R31, R33, R34, and Z are as defined above. a and b are numbers of from 0 to 100, a is preferably from about 0 to about 30 and b is preferably from about 0 to 10, wherein a plus b is at least one, and the EO and PO radicals can be randomly mixed or in discrete blocks.

This chemistry is known to be often used as oilfield corrosion inhibitors.
- The efficacy for corrosion control is often measured by corrosion bubble cell tests. The bubble cell test simulates low flow areas where little or no mixing of water and oil occurs. The test was conducted using brine (80% of the brine having 3% sodium chloride and 20% of the brine being a hydrocarbon containing 100% LVT-200 kerosene oil). The brine was placed into kettles and purged with carbon dioxide. The brine was continually purged with carbon dioxide to saturate the brine prior to starting the test. After the test began, the test cell was blanketed with carbon dioxide one hour prior to electrode insertion and through the duration of the test to maintain saturation. The kettles were stirred at 150 revolutions per minute (rpm) for the duration of the test to maintain thermal equilibrium at 80° C. The corrosion rate was measured by Linear Polarization Resistance (LPR) techniques. The working electrode used was carbon steel. The counter and reference electrodes were both Hastelloy. The electrodes were all cleaned and polished prior to testing.
- Data were collected for three hours before about 4 ppm of each of the tested and control compositions was dosed into its respective cell. Each tested or control composition comprises 10 wt-% of the tested or control compound and 1 wt-% of 2-mercaptoethanol (2ME) as synergist in an organic solvent. The actual concentration of the tested or control compound in each cell was 4 ppm and one of 2ME was 0.4 ppm. Data were collected overnight.
- The results of the bubble cell test are shown in
FIG. 1 and Table 4, wherein ppm is parts per million, CI is corrosion inhibitor, and mpy is mils per year. 0.4 ppm of 2-mercaptoethanol (2ME) were present with each cationic alkyl polyglucoside (APG) compound or control.FIG. 1 shows the corrosion rate in mils per year during the bubble test period (18 hour).
