Abstract

Vegetable-based lubricants are increasingly being used in the USA. Three reasons for this are discussed: the US government's efforts to reduce dependency on conventional energy resources; the promotion of non-food uses for crops; and advances in lubricants technology and genetic enhancement of seed oils. The development of soya-based greases is described. Soya oils tend to show a lack of oxidative stability for use as lubricants and greases. The performance of soya-based greases thickened with clay, aluminium complexes and lithium was studied. Using chemical modifications, addition of antioxidants and/or genetically improved soya beans and the oil was stabilized to handle reaction temperatures required for greases.
