METHOD FOR PREPARING DIORGANOTIN CARBOXYLATES

摘要

Diorganotin carboxylates containing more than one mole of tin for every two moles of carboxylic acid (-?-O-) residues are prepared by a solid state reaction between a diorganotin oxide and a carboxylic acid anhydride. Depending upon the temperature of the oxide-anhydride mixture, the reaction is substantially complete in from less than 1 to up to 48 hours and produces no by-products. The diorganotin compounds of the invention exhibit reduced odor and fuming over the previously known organotin compounds.
