Lubricants derived from plant and animal oils and fats

摘要

A lubricant from plant and/or animal oils and fats; methods for producing a lubricating oil, and the oil produced thereby. The lubricant is derived from an animal or plant fat or oil having an iodine number above about 7, and produced by epoxi-dising the fat or oil and (1) reacting the epoxidised fat or oil with a carboxylic acid anhydride in the presence of a basic catalyst to produce a diester, or (2) hydrogenating the epoxidised fat or oil to generate mono-alcohols and acylating the alcohol functionality with acid anhydrides, acid chlorides or carboxylic acids to produce a mono-ester.
