Improved additives/detergents for lubricant and fuel compositions are obtained by condensing a hydroxyalkyl or hydroxyaryl compound with an amine compound. The condensates according to the present invention are produced by the acid catalyzed condensation of the amine reactant with the hydroxy reactant.
通过将羟基烷基或羟基芳基化合物与胺化合物缩合,可获得用于润滑油和燃料组合物的改良添加剂/清洁剂。本发明的缩合物是通过胺反应物与羟基反应物在酸催化下缩合而制得的。
