Oxidation-resistant cyclophosphazene fluid including triarylphosphine or phosphine oxide

The oxidation resistance of a cyclophosphazene-based fluid (such as a lubricant or a hydraulic fluid) can be improved by the addition to the fluid of an oxidation-inhibiting amount of an aryl phosphine or phosphine oxide. The aryl phosphine or phosphine oxide is preferably present in an amount of about 0.01 to about 5 percent by weight. The aryl phosphine or phosphine oxide can be (a) a symmetric triarylphosphine of formula R 3 P, wherein R is 4-trifluoromethyl phenyl, 3-trifluoromethyl phenyl, 3-trifluoromethoxy phenyl, 3-(3-trifluoromethylphenoxy) phenyl, 3-(perfluoro-2, 5-dimethyl-3, 6-dioxanonyl) phenyl or 1-naphthyl; (b) an oxide of any of these symmetric triarylphosphines; or (c) 1, 3-bis(diphenylphosphino) benzene.
