Abstract

Environmental concerns over the use of petroleum-based products in various industries, such as forestry, farming, mining, boating, and others, has led to increased interest in the use of environmentally friendly fluids. The beneficial aspects of vegetable oils as lubricants are mainly their biodegradability and nontoxicity, which are not exhibited by conventional mineral base oils. Further, vegetable oils have superior solubilizing power for contaminants and additive molecules compared with mineral base fluids.

Certain performance limitations of vegetable oil basestocks are poor oxidative stability due to bis-allylic protons in the fatty acyl chain, deposit forming tendency, low-temperature solidification, and low hydrolytic stability.

Current research efforts are directed toward improving the thermal and low-temperature stability of vegetable oils by chemical modification, blending with functional fluids and additive response studies.
