Abstract:
The present invention relates to novel quaternized ammonium salts of hydrocarbyl epoxides, to the preparation thereof and to the use thereof as a fuel additive and lubricant additive, such as, more particularly, as a detergent additive; for reducing or preventing deposits in the injection systems of direct injection diesel engines, especially in common rail injection systems, for reducing the fuel consumption of direct injection diesel engines, especially of diesel engines with common rail injection systems, and for minimizing power loss in direct injection diesel engines, especially in diesel engines with common rail injection systems; and as an additive for gasoline fuels, especially for operation of DISI engines.

Claim (Index 1):
A reaction product comprising a quaternized nitrogen compound, obtained by a process comprising:\n reacting i) at least one hydrocarbyl epoxide, which is a polyalkylene epoxide that is obtained by epoxidizing a polyalkylene, having a number-average molecular weight (M n ) of 85 to 20,000; with ii) at least one tertiary amine of formula II:\n R a R b R c N \u2003\u2003(II) \n wherein R a , R b  and R c  are each independently a straight-chain or branched, saturated or unsaturated, optionally substituted hydrocarbyl radical, or two of R a , R b  and R c  together with the nitrogen atom to which they are bonded, form an optionally substituted 5- to 7-membered, saturated or unsaturated, nonaromatic or aromatic heterocyclic ring which may optionally bear at least one further ring heteroatom selected from O, S or N; in the presence of iii) at least one acid of formula III:\n H + A \u2212 \u2003\u2003(III) \n in which A \u2212  is the anion of at least one of an inorganic acid and an organic acid selected from the group consisting of C 1 -C 4  monocarboxylic acids, aromatic carboxylic acids, caproic acid, enanthic acid, caprylic acid, pelargonic acid, capric acid, undecanoic acid, lauric acid, tridecanoic acid, myristic acid, pentadecanoic acid, palmitic acid, margaric acid, stearic acid, nonadecanoic acid, arachic acid, behenic acid, lignoceric acid, cerotic acid, melissic acid, monounsaturated fatty acids, diunsaturated fatty acids, triunsaturated fatty acids, tetra- and polyunsaturated fatty acids, ricinoleic acid, gondoic acid, nervonic acid, vernolic acid, malvalic acid, chaulmoogric acid and tall oil fatty acids.
