ABSTRACT:
A process for making a catalyst product which comprises reacting dialkyltin oxide with an alcohol and the corresponding dialkyl carbonate at a temperature in the range between about 50.degree. to 200.degree. C. and at a pressure in the range between about 75 to 600 psi (0.52 to 4.14 MPa), wherein the catalyst product comprises dialkyltin dialkoxide in the range between about 90 to 100 mole % based on the tin species of the catalyst product. This process also forms effective catalyst product when the methanol is replaced with either a primary or secondary alcohol.
