The properties of epoxidized oleochemical methyl esters were studied. Epoxidized soybean oil, epoxidized methyl oleate, epoxidized methyl linoleate, and epoxidized methyl linolenate were compared with each other and with similar series of unmodified olefins. Several interesting trends were uncovered including: epoxidation of olefinic materials improves their oxidative stability, epoxidation of oleochemicals increases their adsorption to metal surfaces, and epoxidation has a deleterious effect on the pour point and viscosity index of the oleochemicals. In addition, a simple qualitative method where lubrication performance can be compared by examination of wear scars generated by ball‐on‐disk friction measurement under a simple optical microscope is reported.
