发明名称 Carbonato aromático, procedimiento de preparación del mismo, y policarbonato preparado usando el mismo
摘要 PURPOSE: A manufacturing method of an aromatic carbonate is provided to able to manufacture an aromatic carbonate with high yield even in low reaction temperature by not using carbon monoxide, but dialkyl carbonate as a reaction raw material. CONSTITUTION: A manufacturing method of an aromatic carbonate comprises a step of reacting an aromatic hydroxy compound and a dialkyl carbonate under the presence of at least one kind or more of samarium based catalysts in chemical formula 1: S_mX_3, or chemical formula 2. In chemical formula 1, X is C1-10 alkoxy, alkylphenoxy, or phenoxy. In chemical formula 2, R1 and R2 is respectively hydrogen or C1-6 alkyl group. The used amount of the catalyst is 1×10^(-5) - 5×10^(-1) mole per 1 mole of the dialkyl carbonate.
