Definitions
- This invention relates to additive concentrates, and to their use to improve the characteristics of fuel oils, especially middle distillate fuels such as diesel fuels, kerosene and jet fuel.
- a fuel oil composition with a sulphur level below 0.05% by weight is referred to herein as a low-sulphur fuel.
- Such low-sulphur fuels may contain an additive to enhance their lubricity.
- additives are of several types.
- WO 94/17160 there is disclosed a low sulphur fuel comprising a carboxylic acid ester to enhance lubricity, more especially an ester in which the acid moiety contains from 2 to 50 carbon atoms and the alcohol moiety contains one or more carbon atoms.
- a mixture of a dimer acid, for example, the dimer of linoleic acid, and a partially esterified polyhydric alcohol is described for the same purpose.
- U.S. Patent No. 3287273 the use of an optionally hydrogenated dimer acid glycol ester is described.
- lubricity enhancers or anti-wear agents as they are also termed, include a sulphurized dioleyl norbornene ester (EP-A-99595 ), castor oil ( U.S. Patent No. 4375360 and EP-A-605857 ) and, in methanol-containing fuels, a variety of alcohols and acids having from 6 to 30 carbon atoms, acid and alcohol ethoxylates, mono- and di-esters, polyol esters, and olefin-carboxylic acid copolymers and vinyl alcohol polymers (also U.S. Patent No. 4375360 ).
- EP-A-99595 sulphurized dioleyl norbornene ester
- castor oil U.S. Patent No. 4375360 and EP-A-605857
- methanol-containing fuels a variety of alcohols and acids having from 6 to 30 carbon atoms, acid and alcohol ethoxylates, mono- and di-esters, polyol esters, and
- Such additives are commonly provided in the form of additive concentrates where the active species is dissolved in a solvent, optionally together with other additives.
- lubricity additives Although largely effective as lubricity additives, it has been found that certain carboxylic acids and carboxylic acid esters, as well as other known lubricity additives, have the disadvantage of poor solubility at low temperature. This poor solubility is found in relation to the solvents used to provide additive concentrates (normally hydrocarbon based), and also in relation to the fuels into which the additive is added. This places a limitation on the storage and use of certain known lubricity additive concentrates at low ambient temperatures.
- EP 0 798 364 A1 describes the use of a salt formed by the reaction between a carboxylic acid and an aliphatic amine to improve inter alia, the lubricity of a diesel fuel.
- the amines used have hydrocarbyl groups of between 2 and 50 carbon atoms, preferably between 8 and 20 carbon atoms, with amines such as oleyl amine being exemplified. There is no discussion of the low temperature behaviour of the salts.
- US 6,277,158 describes a concentrate containing n-butlyamine oleate as a friction modifier for addition to motor gasoline.
- the authors state that despite substantial research investigating a wide range of friction modifier compounds, n-butylamine oleate was one of only two compounds which gave the desired stability over a temperature range, and effectiveness when used in combination with a detergent.
- the concentrate containing n-butylamine oleate is shown to be stable at -20°C for extended periods although there is no indication of the amount of compound present in the concentrate.
- US2002/0095858 relates to fuel oil compositions containing an additive formed by the reaction of a mono- or dicarboxylic acid of 6 to 50 carbon atoms with an amine having at least one branched alkyl substituent. These additives are shown to be effective lubricity enhancers for the fuel. Data are presented showing that the additives per se have good low temperature properties (e.g. pour point) and are stable when held at -25°C for 3 days. To demonstrate an advantageous property of the additives, they are compared to a similar species derived from an amine with linear rather than branched alkyl groups, namely oleic acid neutralised with tri-n-butylamine. The data show that this comparative compound had poorer low temperature properties and crystallised after 3 days at -25°C. There are no data relating to any additive concentrates i.e. compound dissolved in a carrier fluid or solvent.
- a suitable additive may be formed by the reaction of N, N-dibutylamine with an acid mixture consisting of 70% fatty acids and 30% resin-based acids. This additive is shown to be soluble in diesel fuel in an amount of 5% by weight. HFRR data are presented, but there is no discussion of the low temperature properties of the additives.
- the present invention is based on the discovery that additive concentrates containing certain salts derived from certain aliphatic amines have greatly improved low temperature solubility when compared to closely related salts.
- the salts are effective lubricity enhancers for low sulphur content fuels. It is also an advantage that the salts used in the invention have relatively high flash points. This leads to benefits in terms of the ease of, and hazards associated with, their handling and transportation.
- the present invention provides an additive concentrate comprising a lubricity enhancer dissolved in a solvent; wherein the lubricity enhancer comprises from 10 to 90% by weight of the concentrate; wherein the lubricity enhancer comprises a salt formed by the reaction of a carboxylic acid with di-n-butylamine or tri-n-butylamine; and wherein the concentrate remains clear and bright for at least 14 days when held at -30°C.
- the lubricity enhancer comprises from 10 to 80%, more preferably 20 to 80%, for example 33 to 75% by weight of the concentrate and the concentrate remains clear and bright for at least 14 days when held at -30°C.
- the lubricity enhancer comprises from 33 to 50% by weight of the concentrate, and the concentrate remains clear and bright for at least 14 days when held at -40°C.
- the lubricity enhancer comprises from 33 to 50% by weight of the concentrate, and the concentrate remains clear and bright for at least 28 days when held at -30°C.
- the use of the term 'salt' to describe the product formed by the reaction of the carboxylic acid and the amine should not be taken to mean that the reaction necessarily forms a pure salt. It is presently believed that the reaction does form a salt and thus that the reaction product contains such as salt however, due to the complexity of the reaction, it is likely that other species will also be present.
- the term 'salt' should thus be taken to include not only the pure salt species, but also the mixture of species formed during the reaction of the carboxylic acid and the amine.
- di-n-butylamine or tri-n-butylamine is used although mixtures of the two may also be used if desired.
- the salt is formed by the reaction with di-n-butylamine.

- the carboxylic acid comprises tall oil fatty acid (TOFA). It has been found that TOFA with a saturate content of less than 5% by weight is especially suitable. As is known in the art, TOFA contains small but variable amounts of rosin acids and isomers thereof. Preferably, TOFA with an abietic acid content of less than 5% by weight, for example, less than 2% by weight, is used.
- TOFA tall oil fatty acid

- the salt has a flash point of at least 50°C, more preferably at least 60°C.
- the salt may conveniently be produced by mixing the carboxylic acid with the amine.
- the order in which one component is added to the other is not important.
- the molar ratio of the amount of acid to the amount of amine is suitably from 10:1 to 1:10, preferably from 10:1 to 1:2, more preferably from 2:1 to 1:2, for example, around 1:1. In an embodiment, a molar ratio of 1.1:1 to 1:1.1 has been found to be suitable.
- the reaction may be conducted at room temperature, but is preferably heated gently, for example to 40°C.
- the solvent is a hydrocarbon solvent, such as an aromatic hydrocarbon solvent.
- hydrocarbon solvents include petroleum fractions such as naphtha, kerosene, diesel and heater oil; aromatic hydrocarbons such as aromatic fractions, e.g. those sold under the 'SOLVESSO' tradename; alcohols and/or esters; and paraffinic hydrocarbons such as hexane and pentane and isoparaffins.
- the additive concentrate may also contain further additives as required.
- Such further additives include, for example the following: detergents, antioxidants (to avoid fuel degradation), corrosion inhibitors, dehazers, demulsifiers, metal deactivators, antifoaming agents, cetane improvers, co-solvents, package compatibilisers, reodourants, additives to improve the regeneration of particulate traps, middle distillate cold flow improvers and other lubricity additives.

- the fuel oil may comprise atmospheric distillate or vacuum distillate, cracked gas oil, or a blend in any proportion of straight run and thermally and/or refinery streams such as catalytically cracked and hydro-cracked distillates.
- the most common petroleum distillate fuels are kerosene, jet fuels, diesel fuels, heating oils and heavy fuel oils.
- the heating oil may be a straight atmospheric distillate, or it may contain minor amounts, e.g. up to 35 wt %, of vacuum gas oil or cracked gas oil or of both.
- Fischer-Tropsch fuels also known as FT fuels
- FT fuels include those described as gas-to-liquid (GTL) fuels, biomass-to-liquid (BTL) fuels and coal conversion fuels.
- GTL gas-to-liquid
- BTL biomass-to-liquid
- coal conversion fuels coal conversion fuels.
- syngas (CO + H 2 ) is first generated and then converted to normal paraffins by a Fischer-Tropsch process.
- the normal paraffins may then be modified by processes such as catalytic cracking/reforming or isomerisation, hydrocracking and hydroisomerisation to yield a variety of hydrocarbons such as iso-paraffins, cyclo-paraffins and aromatic compounds.
- the resulting FT fuel can be used as such or in combination with other fuel components and fuel types such as those mentioned in this specification.

- FTIR analysis of the reaction product showed a reduction in the strong carboxylic acid peak at 1710cm -1 compared to the starting acid, and a corresponding appearance of carboxylate antisymmetric and symmetric stretches at 1553 and 1399 cm -1 as well as the appearance of a broad range of peaks 2300-2600cm -1 assignable to ammonium species. This was a clear indication of the formation of a salt.

- Example 1 was repeated using tri-n-butylamine in place of di-n-butylamine.
- Tall oil fatty acid, with a saturate content of ca. 2% and a rosin acid content of ca. 1.8%, (TOFA-1) (30.0g, 94.5mmoles) was added to a beaker and with stirring.
- Tri-n-butylamine (17.52g, 94.5mmoles) was then added to the beaker.
- An exotherm of ca. 13°C was measured indicating that the two components reacted.
- FTIR analysis of the reaction product showed a reduction in the strong carboxylic acid peak at 1710cm -1 compared to the starting acid, and a corresponding appearance of carboxylate antisymmetric and symmetric stretches at 1571 and 1371 cm -1 as well as the appearance of a broad range of peaks 2300-2600cm -1 assignable to ammonium species.

- Rape seed oil fatty acid (33.87g) was added to solvent (Atasol 150, 50g) at ca. 30°C and agitated until well mixed. Di-n-butylamine (16.13g) was then charged to the mixture at ambient temperature. An exotherm was observed indicating that the two components reacted. After the exotherm had diminished, agitation was continued for a further four hours. The product was pumped out below the flash point of the solvent.
- Example 1 was repeated using di-n-ethylamine in place of di-n-butylamine.

- the results are given in Table 1 below.
- the data refer to the number of days that the test sample remained clear and bright. All tests were run for a maximum of 28 days, so a result of '28' in the Table does not necessarily indicate a failure on day 28. It is clear from the results obtained that concentrates according to the invention show improved stability at high concentration and low temperature compared to those containing salts produced from either longer or shorter chain length, linear amines.
- salts were produced by reacting n-butylamine with TOFA-1 and TOFA-2 following the same procedure as Examples 1 and 3. Concentrates containing 50wt% in Solvesso 100 showed only very limited stability at -40°C (3 days for the TOFA-1 salt). Concentrates containing 75wt% in Solvesso 100 showed no stability at all at -40°C.
