BORON-CONTAINING HETEROCYCLIC COMPOUNDS AND LUBRICATING OILS CONTAINING SAME

摘要

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