ABSTRACT:
Disclosed are a process for manufacturing metal diaryl dithiophosphates, certain metal diaryl dithiophosphates, and lubricating oil compositions containing said metal diaryl dithiophosphates. The process for the manufacture of metal diaryl dithiophosphate generally comprises reacting P.sub.2 S.sub.5 with a hydroxyl aryl compound to form a dithiophosphoric acid; and neutralizing said dithiophosphoric acid with zinc, barium, cadmium, magnesium or nickel base in the presence of an effective amount of a promoter, said promoter comprising dialkyl dithiophosphoric acid. Metal diaryl dithiophosphates, especially for use in lubricating oil compositions, can be made by the above process.
