COMPOSES HETEROCYCLIQUES UTILISABLES COMME ADDITIFS AUX CARBURANTS AUTOMOBILES ET COMPOSITIONS RENFERMANT LESDITS COMPOSES

摘要

Heterocyclic compounds resulting from the reaction of alkylated or polyoxyalkylated succinic acid or anhydride with a 1-(2-hydroxyethyl-2-alkylimidazoline containing a C7-C21 saturated or unsaturated, linear or branched alkyl group. These compounds are employed as additives in motor vehicle fuels. They make it possible to inhibit the formation of deposits on the inlet valves of spark ignition engines.
