STABILIZER SYSTEMS FOR LUBRICATING FLUIDS

摘要

Lubricating fluids are stabilized against oxidative degradation by the use of a stabilizer system comprising (A) an amine wherein the amine is a substituted benzylamine, or a substituted 1-amino-1,2,3, 4-tetrahydronaphthalene, (B) a metal deacturator and (C) a metal or metal salt. Optionally a metal deactivator can be incorporated into the system. The preferred substitute benzylamine is N( alphamethyl benzyl)aniline the preferred naphthalamine is phenyl-alpha-naphthalamine.
