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.

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

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).

Method for improving the deposit formation resistance performance of turbine oils containing amine antioxidants

A process for preparing alkyl substituted aromatic compounds by alkylating an aromatic compound with an alkylating agent in the presence of a porous crystalline zeolite in which the zeolite has been selectively deluminated to remove nonframework aluminum.

Production of alkylated aromatic compounds using dealuminated catalysts

A biodegradable lubricating oil composition especially useful as a gear oil employs a synthetic alcohol ester basestock formed from mono- and dipentaerythritol with certain mono- and dicarboxylic acids or dicarboxylic acid anhydrides and an effective amount of a polyoxyalkylene alcohol demulsifying agent, a combination of alkylated organic acid and ashless succinimide rust inhibitors and an ashless dithiocarbamate antiwear and extreme pressure agent.

Biodegradable non-toxic gear oil

A catalyst composition is disclosed comprising a zeolite having a non-framework aluminum content of about less than 25 percent of the total aluminum content, a bulk silica:alumina ratio of about 6.5 to about 10.0 and a unit cell size ranging from about 2.440 to about 2.464 nm.
