Abstract
AbstractA new green lubricating base oil was synthesized from soybean oil and triethyl silane by a combination of transesterification and hydrosilylation. The factors affecting the process of hydrosilylation were thoroughly investigated. AlCl3/C catalyst as catalyst for hydrosilylation showed better catalytic performance, and a higher yield of 36.79% was obtained under optimal condition of molar ratio of transesterified soybean oils/triethyl silane (1:1.1), reaction temperature 120°C, and reaction time 8 h. In addition, the performance of silicon‐based soybean base oil was tested according to industry standards. Compared with soybean oil, silicon‐based soybean base oil was obtained with high viscosity index, good pour point of −17°C, and excellent wear characteristic.
