Abstract
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.
