Abstract

Due to the harmful environmental effects caused by the petroleum based lubricants, their replacement with environmental friendly oils has been considered. The aim of this study is to prepare a biological lubricant from Sesame oil during chemical modification using the Trans-esterification reaction and addition of appropriate antioxidant materials. By creating a group of esters on trans position, a product with good lubrication, high viscosity index, high flash point, low pour point, and environmental friendly properties including high degradability and low toxicity were obtained. In the first step, by using an (or of) acetylchloride catalyst, the triglyceride molecules of the Sesame oil were methanolized in a reaction of methanol at 100 ° C in a reflux system. In the next step, the obtained methyl ester in presence of lipase enzyme (as catalyst) by reaction of Trimethylolpropane (TMP) was taken at 50 ° C for 24 hours. Then, different parameters (molar ratio of alcohol to oil, temperature, and enzyme concentration) were evaluated and the best conditions for esterification of Sesame methyl ester with TMP were obtained. Also, some of the physicochemical properties of the lubricants were investigated by using the differential scanning calorimetry (DSC) and viscometry.
