ABSTRACT:
An improved catalytic aromatic carbonate process which comprises contacting under substantially anhydrous reaction conditions a phenol, carbon monoxide, an oxidant, a base, and the Group VIIIB element selected from ruthenium, rhodium, palladium, osmium, iridium or platinum. The resulting aromatic mono- and 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.
