A method for producing an aromatic carbonate, comprising: (1) performing a reaction between an organometal compound and carbon dioxide to obtain a reaction mixture containing a dialkyl carbonate formed by the reaction, (2) separating the dialkyl carbonate from the reaction mixture to obtain a residual liquid, (3) reacting the residual liquid with an alcohol to form at least one organometal compound and form water and removing the water from the organometal compound, and (4) reacting the dialkyl carbonate separated in step (2) with an aromatic hydroxy compound to obtain an aromatic carbonate.
一种生产芳香族碳酸酯的方法,包括:(1)在有机金属化合物和二氧化碳之间进行反应,以获得反应混合物,其中包含通过反应形成的二烷基碳酸酯,(2)从反应混合物中分离出二烷基碳酸酯以获得残留液,(3)将残留液与醇反应,形成至少一种有机金属化合物并形成水,并从有机金属化合物中除去水,(4)将在步骤(2)中分离的二烷基碳酸酯与芳香族羟基化合物反应,以获得芳香族碳酸酯。
