Technical Abstract: The lubricants based on mineral oils render unfavorable impact on the environment. Although not economically viable presently, replacement of hydrocarbon oils with highly biodegradable vegetable oils and their derivatives is on the horizon, due to environmental concerns. However, development of a biodegradable base fluid that could potentially substitute conventional mineral oil poses stiff technical challenges. Seed oils have excellent lubricating properties, but poor oxidation and low temperature stability. This paper presents a systematic approach to improve the existing tribochemical, oxidation and cold flow behavior of seed based oils. A series of structural modification of seed oils using anhydrides of different chain lengths were investigated. The reaction was tracked and products confirmed by NMR and FTIR analysis. Conditions were optimized for laboratory scale-up and potential bulk production.
