Definitions
- the present invention relates to the use of fatty acid salts of alkoxylated oligoamines as lubricity improvers for mineral oil products, in particular for petrol and middle distillates, especially diesel fuels, and also additive concentrates for such mineral oil products and such mineral oil products themselves, which contain these fatty acid salts of alkoxylated oligoamines.
- Carburetors and intake systems of gasoline engines are increasingly contaminated with contaminants caused by dust particles from the air, unburned hydrocarbon residues from the combustion chamber and the crankcase ventilation gases that are led into the carburetor.
- Such pure fuel additives which can originate from a large number of chemical substance classes, such as polyalkenamines, polyetheramines, polybutene-Mannich bases or polybutensuccinimides, are generally used in combination with carrier oils and, in some cases, other additive components such as corrosion inhibitors and demulsifiers.
- Lubricity-improving additives known to date for petrol are, for example, fatty acids, such as. B. described in WO 98/11175, alkenyl succinic acid esters, bis (hydroxyalkyl) fatty amines and hydroxyacetamides.
- fatty acids and fatty acid derivatives e.g. B. esters of glycerol with unsaturated fatty acids, or castor oil, as described in EP-B 605 857, used as lubricity-improving additives.
- the object of the present invention was to provide better-effective lubricity improvers for mineral oil products, in particular for petrol and middle distillates.
- A represents alkylene groups with 2 to 8 carbon atoms, R C to C 3 alkyl groups or mono- or polyunsaturated
- n 0 or an integer from 1 to 5 and
- aqueous lubricants for conveyor belts in the filling of bottles with beverages which contain fatty acid salts of alkanolamines such as N, N, N ', N' tetrakis (2-hydroxypropyl) ethylenediamine.
- alkanolamines such as N, N, N ', N' tetrakis (2-hydroxypropyl) ethylenediamine.
- palmitic acid, tetradecanoic acid, oleic acid and lauric acid are mentioned as fatty acids.
- Mineral oil products are to be understood here as fuels, operating materials, fuels and lubricating oils, which, however, are based not only on petroleum but also partly or completely on synthetic and / or naturally occurring raw materials. Examples of such raw materials are natural gas, methanol, ethanol, hard coal liquefaction products or rapeseed oil, which are processed into fuels or incorporated into petroleum-based fuels.
- the designated mineral oil products are generally practically water-free or contain water at least only in minor quantities.
- Examples of water-containing mineral oil products 38463 4 products are fuel emulsions such as diesel / water emulsions, which can usually contain up to approx. 35% by weight of water.
- Mineral oil products preferred for the present invention are, on the one hand, petrol fuels and, on the other hand, middle distillates such as, in particular, diesel fuels.
- the alkylene group A is preferably derived from corresponding alkylene oxides such as ethylene oxide, 1, 2-propylene oxide, 1,2-butylene oxide and ice or trans-2, 3-butylene oxide. However, it can also represent 1,3-propylene, 1,4-butylene, 1,6-hexylene or 1,8-octylene. A can also represent a mixture of different of the groupings mentioned. A, ethylene, 1,2-propylene or 1,2-butylene groups are particularly preferred for A.
- the longer-chain radical R occurring in the carboxylate anion denotes, for example, branched or preferably linear C - to C 23 -, preferably Cn ⁇ to C 2 ⁇ , especially C 1 5 to C 9 alkyl groups, which may additionally carry hydroxyl groups .
- Examples of the underlying carboxylic acids are octanoic acid, 2-ethylhexanoic acid, nonanoic acid, decanoic acid, undecanoic acid, dodecanoic acid (lauric acid), tridecanoic acid, iso-tridecanoic acid, tetradecanoic acid (myristic acid), hexadecanoic acid (palmitic acid), stearic acid and octadecanoic acid (octadecanoic acid) ,
- the acids mentioned can be of natural or synthetic origin. Mixtures of the acids mentioned can also form the basis of the carboxylate anions.
- the longer-chain radical R occurring in the carboxylate anion preferably denotes mono- or polyunsaturated C 7 to C 3 radicals, in particular mono- or polyunsaturated Cn ⁇ to C 2 ⁇ ⁇ , especially C 15 - to cig alkenyl groups, which can also carry hydroxyl groups.
- These unsaturated residues are preferably linear.
- polyunsaturated alkenyl groups these preferably contain two or three double bonds.
- Examples of underlying carboxylic acids are elaidic acid, ricinoleic acid, linoleic acid and linolenic acid. Particularly good results are achieved with oleic acid.
- Mixtures of such unsaturated carboxylic acids with one another and also with the above-mentioned saturated carboxylic acids can also form the basis of the carboxylate anions.
- Such mixtures are, for example, tall oil, tall oil fatty acid and rapeseed oil fatty acid.
- the unsaturated carboxylic acids and the mixtures mentioned are generally of natural origin.
- variable Z means in particular C 1 -C 4 -alkylene groupings such as methylene, 1, 2-propylene, 1,2-butylene, 1,3-butylene or 2,3-butylene, C 5 - to C 6 -cycloalkylene groupings such as 1,3-cyclo pentylidene or 1,3- or 1, 4-cyclohexylidene or C ß - to Cs-arylene LEN or -Arylalkylengrupp réelleen such as 1,3- or 1, 4-phenylene, 2-methyl-l, 4-phenylene or 1, 3- or 1,4-bismethylene phenylene.
- C 1 -C 4 -alkylene groupings such as methylene, 1, 2-propylene, 1,2-butylene, 1,3-butylene or 2,3-butylene
- C 5 - to C 6 -cycloalkylene groupings such as 1,3-cyclo pentylidene or 1,3- or 1, 4-cyclohexylidene or
- variable m stands for 0, as a rule, depending on the sum (Variablen) of all variables x, mixtures of mono-, di- and / or trialkanolamines or pure trialkanolamines are based on the fatty acid salts used according to the invention as a cationic component.
- alkanolamines are monoethanolamine, diethanolamin, triethanolamine, monoisopropanolamine, diisopropanolamine, triisopropanolamine and the associated mixtures.
- variable m preferably stands for the number 1 or 2.
- m 1 there are completely and / or partially alkoxylated alkylenediamines such as 1,2-ethylenediamine, 1,3-propylenediamine or 1,4-butylenediamine.
- the basis is usually completely and / or partially alkoxylated dialkylenetriamines such as di- (1,2-ethylene) triamine, di- (1,3-propylene) triamine or di- (1,4-butylene) triamine ,
- dialkylenetriamines such as di- (1,2-ethylene) triamine, di- (1,3-propylene) triamine or di- (1,4-butylene) triamine
- OA alkylene oxide units
- over-stoichiometric incorporation a triple alkoxylation per NH bond [300% of (m + 3)] is an upper limit with regard to the properties of the resulting fatty acid salts.
- sub-stoichiometric incorporation an average 50% alkoxylation [50% of (m + 3)] o A corresponding lower limit, in this case there are usually mixtures of species with different degrees of alkoxylation.
- the sum ( ⁇ ) of all variables x has a value of 75% to 125% of (m + 3).
- the fatty acid salts of the general formula I used according to the invention can usually be easily prepared by alkoxylation of the underlying amines by customary methods and subsequent neutralization with the fatty acids of the formula R-COOH.
