METHOD FOR PRODUCING POLYCARBONATE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a polycarbonate in a high yield without using a noxious chlorine gas, phosgene, or a halogenated organic solvent, such as dichloromethane or chloroform, thought to be deleterious to the environment. SOLUTION: The method comprises reacting an aromatic dihydroxy compound or an aliphatic dihydroxy compound with carbon monoxide and oxygen in a nonhalogen solvent in the presence of a catalyst for producing a polycarbonate. The catalyst contains (c) a compound having a redox catalysis and a compound formed by causing (a) an inorganic layered compound to carry (b) palladium. COPYRIGHT: (C)2004,JPO
