ABSTRACT:
A process for the production of alkyltin alkoxides which comprises subjecting at least one alkyltin compound selected from among organotin compounds having tin-oxygen-tin linkages as the starting compound and a hydroxyl compound as the reactant to dehydration to obtain an alkyltin alkoxide corresponding to the starting compound and the reactant, characterized by continuously feeding the starting compound and the reactant into a reactor, discharging a water-containing low boiling point component from the reactor, and continuously withdrawing a reaction fluid containing an alkyltin alkoxide as the bottom from the reactor.
