Transesterification of vegetable oil by ethanol in the presence of heterogeneous catalysts

Abstract

Transesterification of vegetable oil by ethanol in the presence of heterogeneous catalysts has been investigated. Zinc and nickel(II) oxides and cation exchange resin CU-2-8 with immobilized Sn 2+ and Zn 2+ ions were shown to have the highest catalytic activity among an investigated catalysts. The optimal concentration of catalysts and optimal molar ratio triglycerides : alcohol have been established.Кеуwordstransesterification, triglycerides, oxides of metals, cation exchange resin CU-2-8, ethanol.
