Disclosed are novel compounds prepared by reacting two moles of 2,5-dimercapto-1,3,4-thiadiazole and one mole of a hydrocarbon compound selected from terpenes, aryl compounds and aliphatic compounds which may be substituted by oxygen or oxygen containing groups. The hydrocarbon compound forms a bivalent radical linking together the two 2,5-dimercapto-1,3,4-thiadiazoles. The compounds are effective extreme pressure agents when incorporated into lubricating compositions.
所公开的新型化合物是由两摩尔的 2,5-二巯基-1,3,4-
噻二唑和一摩尔的烃类化合物反应制备而成,烃类化合物选自萜烯、芳基化合物和可被氧或含氧基团取代的脂肪族化合物。烃化合物形成一个二价基,将两个 2,5-二巯基-1,3,4-
噻二唑连接在一起。当这些化合物加入润滑组合物中时,可成为有效的极压剂。
