Preparation of silicon‐based soybean base oil by modified soybean oil by transesterification and hydrosilation

Abstract

A 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. AlCl 3 /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.

Direct chemoselective reduction of plant oils using silane catalysed by Rh(iii) complexes at ambient temperature

“…20 Recently, silanes have also been used for the reductive depolymerisation of polyesters using iridium, 21 molybdenum, 22 and zinc-based 23 catalysts to make diols, and for the hydrosilylation of plant oils or fatty acid esters to make silylated esters with potential applications in lubricants. 24…”

Production of esters with numerous applications: Kinetics of Dowex 50W catalyzed transesterification of methyl acetate with three‐ and four‐carbon structured alcohols

“…In the literature, transesterification reactions employing acidic resins, [2,4,5,8,16,[23][24][25][26][27][28][29][30][31] base resins, [32][33][34] mixed resins, [35] ionic liquids, [3,6,[36][37][38] zeolites, [20,39,40] liquid catalysts, [7,[41][42][43][44] and others [45][46][47] have been studied and reported. Many of these catalysts are used for the same transesterification reaction, but they differ in the yield, selectivity, reaction conditions, and reaction time.…”
