Abstract:
The present invention relates to novel quaternized nitrogen compounds, to the preparation thereof and to the use thereof as a fuel and lubricant additive, more particularly as a detergent additive; to additive packages which comprise these compounds; and to fuels and lubricants thus additized. The present invention further relates to the use of these quaternized nitrogen compounds as a fuel 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.

Claim (Index 12):
A process for preparing a quaternized nitrogen compound, the method comprising\n preparing a reaction product by reacting a hydrocarbyl-substituted polycarboxylic acid compound with a compound comprising at least one nitrogen group capable of an addition reaction with the polycarboxylic acid, and comprising at least one quaternizable amino group, to obtain a quaternizable hydrocarbyl-substituted polycarboxylic acid compound, and subsequent reaction thereof with a quaternizing agent which converts the at least one quaternizable amino group to a quaternary ammonium group, said quaternizing agent being the alkyl ester of a cycloaromatic or cycloaliphatic mono- or polycarboxylic acid, especially of a mono- or dicarboxylic acid, or of an aliphatic polycarboxylic acid, especially dicarboxylic acid, wherein said compound comprising said at least one nitrogen group capable of an addition reaction is a N-alkyl-substituted analog of a straight-chain polyamine; reacting a quaternizable hydrocarbyl-substituted polycarboxylic add compound comprising at least one tertiary quaternizable amino group with a quaternizing agent which converts the at least one tertiary amino group to a quaternary ammonium group, wherein said quaternizing agent being the alkyl ester of a cycloaromatic or cycloaliphatic mono- or polycarboxylic acid or of an aliphatic polycarboxylic acid.
