Abstract (en)
[origin: WO2012015873A1] The deposit formation resistance performance of turbine oils containing amine antioxidants and antiwear additives is enhanced beyond the level of that of turbine oils containing tricresyl phosphate antiwear additive by employing as the antiwear additive a 4,4'-(Isopropylidenediphenyl) bis(diphenyl phosphate).
