Technical Abstract: The use of oleochemicals as biobased replacements for petrochemical lubricants is an important area of study. Physical properties of the epoxidized fatty esters derived from vegetable oil are reported and compared to their olefinic counterparts. Overall the frictional behavior of epoxy methyl oleate (EMO), epoxy methyl linoleate (EMLO), and epoxy methyl linolenate (EMLEN) in hexadecane solution were studied and found to reduce friction better than the corresponding olefins. Adsorption coefficients were calculated and the corresponding trends were elucidated. Additionally, the materials have been shown to have improved oxidative stability by Pressure Differential Scanning Calorimetry (PDSC) and Thin Film Micro Oxidation (TFMO). The flow properties of the compounds are also favorable for use as in the lubricant industry. Application of a lubrication fluid of this type is especially useful in areas where a bio-based and environmentally friendly lubricant, such as forestry, would be advantageous.
