  • Method for maintaining antiwear performance of turbine oils containing polymerized amine antioxidants and for improving the deposit formation resistance performance of turbine oils containing monomeric and/or polymeric antioxidants
    Patent number: 8623795
    Abstract: The antiwear performance of turbine oils containing polymerized amine antioxidants and antiwear additives is maintained at or enhanced beyond the level as that of turbine oils containing monomeric amine antioxidants by employing as the antiwear additive a resorcinol bis(diphenylphosphate) (RDP). The deposit formation resistance performance of turbine oils containing monomeric and/or polymeric amine antioxidant is improved by employing RDP.
    Type: Grant
    Filed: July 26, 2011
    Date of Patent: January 7, 2014
    Assignee: ExxonMobil Research and Engineering Company
    Inventors: Michael R. Douglass, Douglas Eugene Johnson, Susan Ardito
  • Method for improving the deposit formation resistance performance of turbine oils containing amine antioxidants
    Patent number: 8618031
    Abstract: 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).
