Succinimides useful as detergents in fuels are prepared by reacting (a) at least one substituted succinic acid or acid derivative thereof containing an average of from 16 to 50 carbon atoms in the molecule and having an acyclic aliphatic substituent group containing an average of at least 12 but less than 30 carbon atoms, with (b) at least one alkanol polyamine containing an average of at least 4 carbon atoms and containing at least one primary amino group. When used as fuel additives, the succinimides are effective in reducing deposits in carburetors and injectors.
可用作燃料清洁剂的琥珀酰亚胺是通过以下反应制备的:(a) 至少一种取代的琥珀酸或其酸衍生物,分子中平均含有 16 至 50 个碳原子,并具有平均含有至少 12 个但少于 30 个碳原子的无环脂族取代基;(b) 至少一种烷醇多胺,平均含有至少 4 个碳原子,并含有至少一个伯氨基。琥珀酰亚胺用作燃料添加剂时,可有效减少化油器和喷油器中的沉积物。
