Boron-containing heterocyclic compounds and lubricating oil containing same

摘要: Certain boron-containing, heterocyclic compounds which impart extreme pressure, anti-wear and friction reducing properties to lubricating oils. Such oils may be further provided with a hydrocarbon polysulfide derivative of 2, 5-dimercapto -1, 3, 4-thiodiazole as copper corrosion inhibitor, or terephthalic acid lead either an alkylated diphenyl amine, bis (dithio-benzil) metal derivative, sulfur bridged, hindered phenol alkyl dialkyl diphenylamine oxidation inhibitor mixture thereof.
