摘要
An enhanced catalytic aromatic carbonate process which comprises contacting a phenol, carbon monoxide, an oxidant, a base, the Group VIIIB element selected from ruthenium, rhodium, palladium, osmium, iridium or platinum, and a manganese tetradentate redox co-catalyst. The resulting aromatic mono- and/or poly-carbonates are useful in the preparation of polycarbonates or as polycarbonates per se, respectively, which can be molded or formed into films, sheets, fibers, laminates or reinforced plastics by conventional techniques.
