Palyukh Z. The basics of triglycerides transesterification technology in the presence of divalent metals ions

The results of regularities of the transesterification reaction of triglycerides by C2–C5 alcohols in the presence of salts of divalent metals and cation exchange resin KU-2-8 containing immobilized ions Zn(2+), Ni(2+), Sn(2+), Co(2+), Cu(2+) are presented. The influence of the structure of alcohol and triglyceride, the effect of temperature, the type and content of the catalyst, the molar ratio of the reagents, the presence of impurities in the reaction mixture on the conversion of triglycerides and the optimal conditions of the process for obtaining esters of higher fatty acids and these alcohols were researched. Principal technological schemes of the periodic process for obtaining esters of unsaturated fatty acids based on C2–C4 alcohols are proposed.
