A novel transesterification catalyst and a process for the preparation thereof

摘要

The present invention provides a novel transesterification catalyst having the general formula: ZnM(CN)(ROH).xZnCl.yHO wherein R is tertiary-butyl and M is a transition metal ion selected from Fe, Co and Cr, x varies from O to 0.5, y varies from 3-5 and n is 10 or 12. The above said catalyst is useful for an efficient transesterification of glycerides, fatty acid esters and cyclic carbonates on reactions with alcohols.
