    Abstract: A diesel fuel composition comprising a major portion of middle distillates and a minor wear improving amount of a 1,3,4-thiadiazole derived from 2,5-dimercapto-1,3,4-thiadiazole and one or two moles of polyolefin having 50 to 400 carbon atoms. Furthermore, the 5-position of the 2-mercapto-1,3,4-thiadiazole may be substituted by alkylthio, 2-hydroxyalkylthio, amino or hydroxy group. The 1,3,4-thiadiazole compounds are also effective dispersants when incorporated into fuel compositions.

    Abstract translation: 一种柴油燃料组合物,其包含主要部分的中间馏分和少量改善磨损量的由2,5-二巯基-1,3,4-噻二唑衍生的1,3,4-噻二唑和1或2摩尔的具有50 至400个碳原子。 此外,2-巯基-1,3,4-噻二唑的5-位可以被烷硫基,2-羟基烷硫基,氨基或羟基取代。 当并入燃料组合物中时,1,3,4-噻二唑化合物也是有效的分散剂。
