Procedure

Dibutyltin oxide is reacted with methanol and dimethyl carbonate, at a temperature in the range between about 50° to 200° C. and at a pressure in the range between about 75 to 600 psi (0.52 to 4.14 MPa) resulting in a quantitative formation of dibutyltin dimethoxide (i.e., dibutyltin dimethoxide is present in the final product in an amount between about 90 to 100 mole % (based on tin species in the catalyst product), more preferably about 95 to 100 mole %) and carbon dioxide as shown in Equation 4 below: ##STR4##
