  • Patent number: 4428848
    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.

  • Patent number: 3954577
    Abstract: Aluminum bromide is prepared by an electrochemical process in a cell with an aluminum anode, employing as the electrolyte, a solution of hydrogen bromide in an aprotic solvent capable of dissolving both hydrogen bromide and aluminum bromide. After initiation of the reaction with an electric current, the reaction proceeds without additional electrical power. The product is a solution of aluminum bromide and may also include solid aluminum bromide if the amount produced exceeds the solubility limit of the solvent.
