    摘要: A non-aqueous lubricating oil composition comprises a major amount of a base oil and a minor amount of an additive which is present in solution in the base oil and is a non-halide, non-aromatic ionic liquid which is a salt of general formula C+A−, with the cation, C+, being a quaternary phosphonium or quaternary ammonium ion having four hydrocarbyl groups, optionally containing heteroatoms, which hydrocarbyl groups do not all have the same number of carbon atoms, there being at least one long chain hydrocarbyl group having greater than 4 carbon atoms and at least one short chain hydrocarbyl group having fewer carbon atoms than each of the long chain hydrocarbyl groups, and the anion, A−, comprising at least one oxygen atom and having an ionic head group attached to at least one alkyl or alicyclic hydrocarbyl group which has at least four carbon atoms and optionally at least one heteroatom. The ionic liquid may be used as an anti-wear component in a lubricating oil composition. The ionic liquid may be used as a friction modifier in the lubricating oil composition. The lubricating oil composition may be used in an ignition engine.

    摘要: The present invention relates to a lubricating basestock for the blends of hydrofluorocarbon and optionally hydrochlorofluorocarbon refrigerants comprising a blend of (A) at least one alkylbenzene and (B) at least one polyol ester. While alkylbenzenes are not miscible with the refrigerant blend at the desired operating temperature and pressure of refrigeration or air-conditioning systems, the addition of low concentration of polyol ester is found to greatly improve the miscibility of the alkylbenzene and polyol ester blend. An important criteria of the invention is that the lubricant blend of polyol ester and alkylbenzene are sufficiently miscible with the hydrofluorocarbon refrigerant blend both as a liquid and a gaseous refrigerant over the operational temperatures of the compression refrigeration system.
