  Quaternary ammonium salts of formula: wherein each of R1 and R2 is independently selected from an optionally substituted alkyl, alkenyl or aryl group having less than 8 carbon atoms, R together with N forms an aliphatic or aromatic heterocycle having less than 12 carbons atoms and R5 is hydrogen or an optionally substituted hydrocarbyl group. The use of these compounds as fuel or lubricant additives, especially as diesel fuel additives.

  式中 R1 和 R2 各自独立地选自具有小于 8 个碳原子的任选取代的烷基、烯基或芳基，R 与 N 一起形成具有小于 12 个碳原子的脂肪族或芳香族杂环，R5 为氢或任选取代的烃基。这些化合物可用作燃料或润滑油添加剂，尤其是柴油添加剂。
