Abstract: Methods for recovery of concentrates of lubricating compounds and biologically active compounds from vegetable and animal oils, fats and greases that allow separation of triglycerides, from components with higher lubricity or biological activity or enrichment protocols that increase the concentration of high lubricity or biologically active compounds in the triglyceride. The triglycerides are transesterified with a lower alcohol to produce alkyl esters. Following the conversion process the esters are separated from high molecular weight high lubricity compounds and biologically active compounds by distillation. The esters have some lubricity and may be sold as pollution reducing fuel components.

The triglycerides are transesterified with a lower alcohol to produce alkyl esters. Following the conversion process the esters are separated from high molecular weight high lubricity compounds by distillation. The esters have some lubricity and may be sold as pollution reducing fuel components. The high boiling point compounds that are the residues of distillation, however, can contribute significant lubricity and may be used widely in lubricant applications or added to petroleum fuels to decrease friction.
