Abstract:
A cyclophosphazene fluid composition containing organometallic or inorganic metal salts as antioxidants the antioxidants for use therein, and a method therefor, are disclosed herein. Suitable organometallic salts are formed by reacting a metal hydroxide with benzoic acid, substituted benzoic acids, or substituted phenols. The preferred inorganic metal salts effective for this purpose include various metal borates. The metal salt antioxidants are effective for reducing oxidation in the cyclophosphazene fluid in amounts of less than about 1% by weight of the overall composition.

Abstract:
An immersion oil for use in microscopy having a high refractive index and a high principal dispersion factor without the inclusion of polychlorinated biphenyls (PCB's) and terpenyls. The immersion oil being a mixture of a low molecular weight hydrocarbon resin diphenyl isodecyl phosphite, and one or more of polybutylene, mineral oil, and trilauryl trithio phosphite.
Abstract:
A composition comprising 96-99.9% by weight of a highly flame-resistant base oil such as an aromatic phosphate ester or a polychlorinated aromatic compound and a polyester of molecular weight, 20,000 to 300,000, derived from polytetramethylene glycol, for instance. The composition has an improved viscosity index and is especially useful as a HSD lubricant. It is also useful as a hydraulic fluid and/or heat transfer liquid. By addition of such a polyester to such base oil, the viscosity index of the base oil is considerably improved.
Abstract:
The addition of a small amount of a phosphate ester soluble amine salt of a perfluoroalkane sulfonic acid or a perfluoroalkane disulfonic acid to an energy-transmitting functional fluid greatly enhances the anti-erosion properties of the fluid.
