PRODUCTION OF AROMATIC CARBONATE ESTER

摘要

PURPOSE:To produce an aromatic carbonate ester in the presence of a small amount of a catalyst in a short time in high yield and in high concentration by reacting an aromatic hydroxy compound with carbon monoxide and oxygen. CONSTITUTION:The reaction is performed in the presence of (A) palladium or a palladium compound, (B) one or more kinds of manganese compounds, (C) one or more kinds of cobalt compounds, (D) one or more kinds of quaternary ammonium salts or quaternary phosphonium salts, and (E) one or more kinds of aromatic diols comprising quinone compounds and their reduced products.
