A method for producing a carbonic ester, comprising: (1) performing a reaction between an organometal compound mixture and carbon dioxide, the organometal compound mixture comprising a reactive organometal compound and an unregenerable unreactive compound derived from the reactive organometal compound, to thereby obtain a reaction mixture containing a carbonic ester, the unregenerable unreactive compound, and a regenerable metamorphic organometal compound derived from the reactive organometal compound, (2) separating the reaction mixture into a first portion containing the carbonic ester and the unregenerable unreactive compound, and a second portion containing the regenerable metamorphic organometal compound, and (3) reacting the second portion of the reaction mixture with an alcohol to form an organometal compound mixture and water and removing the water from the organometal compound mixture, the organometal compound mixture comprising a reactive organometal compound and an unregenerable unreactive compound derived from the reactive organometal compound.
一种生产碳酸酯的方法,包括:(1)在含有反应性有机金属化合物和不能再生的不活性化合物的有机金属化合物混合物和二氧化碳的反应中,得到包含碳酸酯、不能再生的不活性化合物和可再生的变形有机金属化合物的反应混合物;(2)将反应混合物分离成包含碳酸酯和不能再生的不活性化合物的第一部分和包含可再生的变形有机金属化合物的第二部分;(3)将反应混合物的第二部分与醇反应,形成有机金属化合物混合物和水,并从有机金属化合物混合物中去除水,所述有机金属化合物混合物包括反应性有机金属化合物和来源于反应性有机金属化合物的不能再生的不活性化合物。
