ABSTRACT:
Improved lubricating oil for high pressure polyethylene compressors contains white mineral oil or synthetic oil blended with oleic acid in an amount less than 15 wt %, and preferably 0.5-5 wt. %, an EP additive such as a phosphorus containing compound made by phosphating mono or diglycerides derived from vegetable oils and having one or two neutralized acid sites, and no more than 1.0 wt. %, and preferably no more than 0.1 wt. %, of an antioxidant of the phenolic type, and a polybutene viscosity builder in the amount necessary to achieve the expected or desired viscosity. The lubricating compressor oil according to the invention has improved lubricity and gives wear protection over the whole range of lubricating regimes including EP conditions.
