Patent ID: 7629485

Claim:
A method for producing an aromatic carbonate, which comprises allowing to react a starting material selected from the group consisting of a dialkyl carbonate represented by the following formula (1), an alkylaryl carbonate represented by the following formula (2) and a mixture thereof with a reactant selected from the group consisting of an aromatic monohydroxy compound represented by the following formula (3), an alkylaryl carbonate represented by the following formula (4) and a mixture thereof in the presence of a metal-containing catalyst, while distilling off by-product alcohols and/or by-product dialkyl carbonates to the outside of the reaction system, thereby producing an aromatic carbonate represented by the following formula (5) and/or the following formula (6) corresponding to the starting material and the reactant, wherein the metal-containing catalyst is an organic polytitanoxane compound of a molecular weight of 480 or more which comprises at least two titanium atoms and is dissolved in a liquid phase in the reaction system or present in the form of liquid during the reaction, wherein R 1 , R 2 and R 3 in the formulas (1) to (4) independently represent an alkyl group having 1 to 10 carbon atoms, an alicyclic group having 3 to 10 carbon atoms or an aralkyl group having 6 to 10 carbon atoms, and Ar 1 , Ar 2 and Ar 3 independently represent an aromatic group having 5 to 30 carbon atoms, and wherein R in the formula (5) is selected from R 1 , R 2 , R 3 of the corresponding starting material and reactant, and Ar in the formulas (5) and (6) is selected from Ar 1 , Ar 2 and Ar 3 of the corresponding starting material and reactant, respectively.
