摘要： A method for producing an aromatic carbonate is characterized by having the following steps (1)-(4): (1) an organic metal compound and carbon dioxide are reacted, thereby obtaining a reaction mixture containing a dialkyl carbonate formed by the reaction; (2) the dialkyl carbonate is separated from the reaction mixture, thereby obtaining a residual liquid; (3) the residual liquid is reacted with an alcohol, thereby forming at least one kind of organic metal compound and water, and the water is removed from the organic metal compound; and (4) the dialkyl carbonate separated in the step (2) is reacted with an aromatic hydroxy compound, thereby obtaining an aromatic carbonate.

摘要： 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 component from the reactor, and continuously withdrawing a reaction fluid containing an alkyltin alkoxide as the bottom from the reactor.
