Chemically modified seed oils via acylation of epoxidized and polyhydroxylated derivatives were investigated for their potential as candidates for lubrication. The native oil was preliminarily epoxidized and ring-opened in a one-pot reaction using formic acid-H2O2 followed by aqueous HCl treatment to give the polyhydroxy intermediate. The latter was then acylated with C-2 to C-5 anhydrides to avail the poly-acetyl, poly-butyroyl and poly-pentanoyl esters of the oil. Using oxirane as a starting material, the vicinal polyformates were generated. A tribological study of these seed oil derivatives exhibited low coefficient of friction as well as low wear scar in the 4-ball tribometric tests.
