Definitions
- the present invention relates to novel organic liquid compositions, and particularly to volatile organic liquids of increased electrical conductivity.
- Volatile organic liquids have long been essential commodities in our present industrial economy. Indeed, most of the many familiar industrial achievements of today would have been impossible without them. Volatile organic solvents are extensively used in chemical processes, such as in extraction and crystallization; in the manufacture of paints and other coatings, plastics, inks, linoleum, insecticides, adhesives, paper, dyes, pharmaceuticals and many other natural and synthetic chemical products; and in cleaning operations of all kinds, such as dry cleaning of fabrics, degreasing of metals and cleaning of machinery and tools. There is virtually no part of present day industry in which it is not desirable to use these solvents for one purpose or another. Additionally, volatile organic liquid fuels, for example, gasoline, are so extensively used that they now supply a very large proportion of the total energy consumption of the world.
- This type of liquid level measuring device is advantageous also in open vessels or in closed vessels not under pressure because it eliminates the float, which is mechanically vulnerable and is often in the Way, especially during batch operations such as fabric cleaning and the like.
- increasing the conductivity of carbon tetrachloride, for example would not be useful from the standpoint of reducing the likelihood of its catching fire from spark discharge of static electricity, it would be highly useful and advantageous by making possible the use of an electrode type of liquid level measuring device.
- a further object of the invention is to provide an economical method for minimizing the propensities of such liquids for the accumulation of static electrical charges.
- Another object of the invention is to provide volatile organic liquid compositions of increased electrical conductivity.
- Still another object of the invention is to provide volatile liquid organic compositions the electrical conductivity of which has been effectively increased by the addition of less than the usual quantities of conductivity additives.
- the conductivity of volatile organic liquids is increased by dissolving therein two additives, the first of which (hereinafter referred to as Additive A) is a polyvalent metal organic salt having a molecular weight of at least 200, and the second of which (hereinafter referred to as Additive B) is an oxygenated (i.e., oxygen-containing) organic compound having a molecular weight of at least 200, and the product of the molecular weight of which times the specific conductivity (in the units, ohm-' cm.- of which in benzene, at a concentration of one gram per liter, is at least l 10- and which furthermore contains no ion common to Additive A, namely, the organic polyvalent metal salt.

- Additive B an oxygenated organic compound having a molecular weight of at least 200

- the organic liquid into which the combination of substances for increasing electrical conductivity is incorporated is one which has a dielectric constant at 20, C. of less than 9, and preferably less than 7, and substantially all of which (i.e., at least 90 mol percent) consists of a compound or mixture of compounds having no more than 12 carbon atoms per molecule and preferably no more than 10 carbon atoms per molecule.
- the preferred class of such volatile organic liquids consists of hydrocarbons; however, also suitable are halogenated hydrocarbons, preferably containing up to 4 halogen atoms, preferably bromine and/ or chlorine, per molecule, nitrated hydrocarbons, preferably those containing no more than one nitrogen atom per molecule, and hydrocarbyl ethers Preferably containing no more than 2 atoms of oxygen per molecule, and especially such volatile organic liquids which are inflammable.
- the invention is of particular importance for the very volatile and inflammable hydrocarbon liquids, such .4 as those having flash points (ASTM Test Method D-56) below about F., since with these liquids the danger of ignition or explosion occurring as a result of electrical charges is particularly great.
- organic liquids suitable for the purpose of this invention are aliphatic hydrocarbons or mixtures thereof, such as hexane, heptane, etc.; aromatic hydrocarbons or mixtures thereof such as benzene, toluene, the xylenes; cyclo-aliphatic hydrocarbons, for example decalin and cyclohexane; mixtures of the various types (aliphatic, cycloaliphatic and aromatic) of hydrocarbons; halogenated hydrocarbons, for instance chloroform, carbon tetrachloride, trichloroethylene, tetrachloroethylene, and ethers, for example diethyl ether and dioxane.
- aliphatic hydrocarbons or mixtures thereof such as hexane, heptane, etc.
- aromatic hydrocarbons or mixtures thereof such as benzene, toluene, the xylenes
- cyclo-aliphatic hydrocarbons for example decalin and
- Liquid mixtures of which one of the components as such possesses a dielectric constant of 9 or more are also suitable, provided the dielectric constant of the whole mixture is less than 9.
- An example of such a mixture is a mixture of benzene with a minor proportion of nitrobenzene.
- the invention is applicable and beneficial particularly in the case of all of the volatile liquid petroleum products substantially all of which consist of hydrocarbons having no more than 12 carbon atoms per molecule, for example, gasoline, VM and P naphtha, cleaners naphtha, lighter fluid, mineral spirits, rubber solvent, lacquer diluent, and special low boiling range solvents of all kinds such as direct cuts of xylenes and non-aromatics boiling in or near the xylene range, or similar toluene or benzene cuts, or iso-pentane cuts.

- Substituted or unsubstituted aliphatic, cyclo-aliphatic and aromatic mono or polycarboxylic acids are suitable.
- monovalent or polyvalent, substituted or unsubstituted phenols, naphthols and sulfonic acids are suitable.
- the preferred class of compounds suitable as Additive A consists of the salts of aliphatic and aromatic carboxylic and sulfonic acids.
- a salt of one of the above-defined organic acids and any polyvalent metal is suitable as long as the molecular weight of the salt is at least 200 and preferably not more than about 1500.
- the polyvalent metal have a valence of either 2 or 3 in the salt.
- Polyvalent metals having atomic num' bers of from 12 through 29 are particularly effective.
- suitable polyvalent metals are the alkaline earth metals (calcium, magnesium, strontium, barium), copper, zinc, cadmium, aluminum, lead, chromium, molybdenum, manganese, iron, cobalt and nickel. Of these the alkaline earth metals are especially preferred, but those metals having a valence of from 2 through 3 as well as an atomic number of from 12 through 29 are exceptionally effective.
- Additive A are the salts of the higher fatty acids, for instance calcium oleate and magnesium oleate; the salts of substituted higher fatty acids, for example calcium phenyl stearate; the salts of alkyl-substituted aromatic carboxylic acids, for example of alkylated salicylic acids, such as diisopropyl salicylic acid or salicylic acids substituted with longer alkyl groups, for example alkyl groups with 14 to 18 carbon atoms; the salts of the sulfonated dialkyl esters of aliphatic dicarboxylic acids, for example, the sulfonated dioctyl ester of succinic acid; the salts of petroleum sulfonic acids,
- substituted phenol-formaldehyde condon Sation products such as the calcium salt of an octyl' phenol formaldehyde condensation product.
- Additive A is added to the organic liquid in quantities which may vary within relatively wide limits. In general a satisfactory increase of the electrical conductivity of the organic liquid is obtained if the particular Additive A is dissolved in the organic liquid (in combination with Additive B) in a concentration of less than 0.001 gram mole per liter. In most cases concentrations of in general only small quantities of Additive B too, need be dissolved therein to obtain the desired increase in the specific conductivity. In most cases concentrations of Additive B of from about 1x10 to about 1 1O- gram the polyvalent metal salt lying between 1x10 and mole per liter are suificient. If desired, however, larger 1X10- gram mole per liter will be sumcient.
