A turbine lubricant having outstanding oxidation stability, corrosion resistance and good viscosity stability is based on a liquid mixed isopropylphenyl/phenyl phosphate ester and contains small amounts of an amine selected from the group consisting of phenyl-.alpha.-napthyl-amine, phenyl-.beta.-naphthylamine, and diphenylamine; benzotriazole, and a corrosion inhibitor selected from the group consisting of oleylsarcosine, epoxidized soybean oil, and a mixed mono- and dialkyl phosphate of the formula RH.sub.2 PO.sub.4 and R.sub.2 HPO.sub.4, wherein R is an alkyl group of 8-12 carbon atoms.

Turbine lubricant

A turbine lubricant having outstanding oxidation stability, corrosion resistance and good viscosity stability is based on a liquid mixed isopropylphenyl/phenyl phosphate ester and contains small amounts of bis[4-(dimethylamino) phenyl]methane, benzotriazole and a mixed mono- and dialkylphosphate of the formula RH.sub.2 PO.sub.4 and R.sub.2 HPO.sub.4, wherein R is an alkyl group of 8-12 carbon atoms.

There are disclosed triaryl phosphate ester functional fluids, such as lubricants and hydraulic fluids, which contain as the oxidatively stable component, a mixed tertiary-butylphenyl/phenyl phosphate containing about 15 to 60% by weight t-butylphenyl radicals.

Triaryl phosphate ester functional fluids

There are disclosed, as novel compounds, high molecular weight hindered phenols based on the condensation of a nitroalkane with either formaldehyde and di-t-butylphenol or with a substituted derivative of a di-t-butylphenol. The compounds are generally useful as antioxidants for a wide variety of organic substrates.
