ABSTRACT:
A functional fluid composition consisting essentially of (1) a phosphorus compound, preferably a phosphate ester containing at least two alkyl groups such as tributyl phosphate or di-n-butyl phenyl phosphate, alone or particularly in combination with a phosphate ester containing at least two aromatic groups, such as n-butyl diphenyl phosphate or tricresyl phosphate, (2) a polyalkylene glycol material, e.g. a polypropylene glycol ether having a molecular weight ranging from about 600 to about 1200, and particularly a combination of at least two polyalkylene glycol materials, e.g. two polypropylene glycol ethers having substantially different molecular weights, (3) a dicarboxylic acid ester, e.g. a diester of adipic acid such as diisodecyl adipate, and (4) a small amount of certain halogenated organic selenides or tellurides, preferably a chlorinated aryl selenide such as 4,4'-dichlorodiphenyl diselenide, or a chlorinated selenophene or a chlorinated tellurophene, e.g. tetrachloroselenophene or tetrachlorotellurophene.
