Thallium compounds as catalysts for transesterifications and ester exchange reactions
SummaryThe transesterification of di-, tri-and tetracarboxylic alkyl esters with 2,3-epoxypropanol was investigated in the presence of various metal compounds as catalysts. It was found that only thallium compounds catalyse the reactions under mild conditions without decomposition of 2,3-epoxypropanol. Many thallium compounds also proved to be very good catalysts for the reactions of 2,3-epoxypropanol with alkoxysilanes and the ester exchange reactions of di-, tri-and tetracarboxylic alkyl esters with 2,3-epoxypropyl-acetate.
