摘要： A method for preparing an aromatic carbonate, of the present invention, comprises the steps of: (A) preparing a reaction mixture containing an aliphatic carbonate by reacting an organometallic compound and carbon dioxide; and (B) preparing an aromatic carbonate by reacting the reaction mixture and an aromatic alcohol. The method for preparing an aromatic carbonate allows an aromatic carbonate to be economically prepared in a high yield by using carbon dioxide as a carbonyl supply source.

摘要： A method for preparing a carbonic ester includes reacting carbon dioxide and a C1 to C10 alcohol with an organometallic compound represented by Formula 1. With the method, carbonic ester can be prepared in high yield without recycling the organometallic compound. M(OR1)4  [Formula 1] wherein M is a Group IV or Group XIV element and each R1 is independently a C1 to C10 hydrocarbon group.
