摘要:
Die vorliegende Erfindung betrifft neuartige säurefreie quaternisierte Stickstoffverbindungen, deren Herstellung und Verwendung als Krafts- und Schmierstoffadditiv, wie insbesondere als Detergensadditiv, als Wachs-Anti-Settling-Additiv (WASA) oder als Additiv zur Verringerung der inneren Dieselinjektorablagerungen (IDID); Additivpakete, welche diese Verbindungen enthalten; sowie damit additivierte Kraft- und Schmierstoffe. Weiterhin betrifft die vorliegende Erfindung die Verwendung dieser säurefreien quaternisierter Stickstoffverbindungen als Kraftstoffzusatz zur Verringerung oder Verhinderung von Ablagerungen in den Einspritzsystemen von direkteinspritzenden Dieselmotoren, insbesondere in Common-Rail-Einspritzsystemen, zur Verringerung des Kraftstoffverbrauches von direkteinspritzenden Dieselmotoren, insbesondere von Dieselmotoren mit Common-Rail-Einspritzsystemen, und zur Minimierung des Leistungsverlustes (powerloss) in direkteinspritzenden Dieselmotoren, insbesondere in Dieselmotoren mit Common-Rail-Einspritzsystemen.

The invention relates to a quaternized copolymer, which can be obtained by: (A) copolymerizing straight-chain, branched or cyclic ethylenically unsaturated C2 to C100 hydrocarbons, which can bear oxygen-functional or nitrogen-functional substituents which cannot be reacted with amines to obtain amides or imides, or with alcohols to obtain esters, with ethylenically unsaturated C 3 - to C 12 -monocarboxylic acids or -dicarboxylic acids, or derivatives thereof, which can be reacted with amines to obtain amides or imides, or with alcohols to obtain esters, to obtain a copolymer having a number average molecular weight of 500 to 20,000; (B) partially or fully amidating or imidating or esterifying the carboxylic acid functions by reaction with oligoamines having 2 to 6 nitrogen atoms or alcohol amines, which each contain a primary or secondary nitrogen atom or a hydroxyl group and a quaternizable tertiary nitrogen atom; (C) partially or fully quaternizing the tertiary nitrogen atom with a quaternizing agent. The quaternized copolymer thus produced is suitable as a fuel additive in direct-injection diesel engines.
