    • The present invention relates to a method of producing an aromatic carbonate by reacting an aromatic hydroxy compound, carbon monoxide and oxygen using a catalyst system for suppressing the production of aryl aromatic o-hydroxycarboxylate as a by-product. The catalyst system consists of the following compounds:(A) at least one selected from palladium and palladium compounds;(B) at least one selected from lead compounds; and(C) at least one halide selected from quaternary ammonium halides and quaternary phosphonium halides; and if required,(D) at least one selected from copper and copper compounds.The method of the present invention can increase the yield of an aromatic carbonate per palladium (the turnover number of palladium).
    • 本发明涉及通过芳香族羟基化合物,一氧化碳和氧气的反应来制造芳香族碳酸酯的方法,该催化剂体系用于抑制作为副产物的芳基芳族邻羟基羧酸酯的生产。 催化剂体系由以下化合物组成:(A)选自钯和钯化合物中的至少一种; (B)选自铅化合物中的至少一种; 和(C)选自季铵卤化物和季鏻卤化物的至少一种卤化物; 如果需要,(D)选自铜和铜化合物中的至少一种。 本发明的方法可以提高每钯的芳族碳酸酯的收率(钯的转换数)。
