A middle distillate fuel additive comprising the reaction product resulting from the combining of a hydrocarbyl succinic anhydride and a hydroxyamine. The lubricating properties of low sulfur-content middle distillate fuels, such as diesel, jet or bio-diesel fuels, can be significantly improved by inclusion therein of such additive compounds. The use of these middle distillate fuel additives makes it possible to avoid mechanical failure problems, such as fuel pump or injector failure, otherwise caused by inadequate fuel lubricity, while still retaining the environmental benefits of using a low sulfur fuel.
一种中间馏分燃料添加剂,由烃基丁二酸酐和羟胺结合产生的反应产物组成。在低含硫量的中间馏分燃料(如柴油、喷气燃料或生物柴油)中加入此类添加剂化合物,可显著改善其润滑性能。使用这些中间馏分燃料添加剂可以避免因燃料润滑性不足而导致的机械故障,如燃油泵或喷油器故障,同时还能保持使用低硫燃料的环保优势。
