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. Oxidation results in increased acidity, corrosion, viscosity, and volatility of the lubricant. On the other hand, parameters like lubricity, antiwear protection, load carrying capacity, mst prevention, foaming, demulsibility, etc., are mostly additive dependent. Antioxidant additives (4) provide limited improvement of oxidative stability therefore, other approaches are required to improve the above characteristics.
