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 Sn2+ and Zn2+ 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.
