Abstract
Disclosed are novel compounds prepared by the reaction of an adduct of a phosphosulfurized polyisoalkylene or alpha olefin with an acidified hexavalent molybdenum salt which give enhanced copper corrosion protection relative to the non-molybdenum treated adducts when incorporated in lubricants. Also disclosed is the combination of such compounds with a zinc dialkyldithiophosphate, which combination imparts to lubricants an oxidation inhibition greater than is obtainable with either the zinc dialkyldithiophosphate or the molybdenum-containing adduct alone.
