Technical Abstract: Vegetable oils possess a number of desirable properties for lubricant application such as excellent boundary properties, high viscosity index, low volatility, low traction coefficient, renewability, and biodegradability. Unfortunately, they also have a number of weaknesses that make them less desirable for lubricant applications. Examples of such weaknesses include poor oxidation stability, unacceptably high pour point and cloud point, poor hydrolytic stability, and low biostability. Various approaches are being investigated to improve the inherent weaknesses of vegetable oils without negatively impacting their desirable properties. In the work described here, vegetable oils were chemically modified and their tribological properties investigated. The result showed that chemical modification can improve oxidation and cold flow properties of vegetable oils without causing serious negative impact on other tribological properties.
