CA 2625437

The present invention provides a novel transesterification catalyst having the general formula: Zn3M2(CN)n(ROH).xZnCl2.yH2O 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.

L'invention concerne un nouveau catalyseur de transestérification représenté par la formule générale: Zn3M2(CN)n(ROH).xZnCl2.yH2O, dans laquelle R représente un butyle tertiaire et M représente un ion de métal de transition sélectionné dans Fe, Co et Cr, la valeur de x étant comprise entre 0 et 0,5, celle de y entre 3 et 5 et n étant égal à 10 ou 12. Le catalyseur en question est utilisé pour mener une transestérification efficace de glycérides, d'esters d'acides gras et de carbonates cycliques à partir de réactions avec des alcools.
