摘要：PROBLEM TO BE SOLVED: To provide an industrially advantageous method for producing a carbonic ester with which an organometallic compound can simply and efficiently be recycled and recovered from a reaction system and the carbonic ester can continuously be obtained and to provide a method for efficiently producing the organometallic compound from an organometallic oxide. SOLUTION: The organometallic compound is used to synthesize the carbonic ester from carbon dioxide and an alcohol. The used organometallic compound is reacted with the alcohol in the presence of the carbon dioxide and a dehydrating agent to recycle the organometallic compound. The resultant organometallic compound is then circulated for use in a step of synthesizing the carbonic ester. COPYRIGHT: (C)2006,JPO&NCIPI
