RD-11,457 ABSTRACT OF THE DISCLOSURE A carbonylation process which comprises contacting a .beta.-fluoroalkanol. carbon monoxide, a base, and the Group IIB element mercury present in an oxidation state greater than zero. The resulting .beta.-fluoroaliphatic carbonates can be employed in combi-nation with alkanols and/or phenols to prepare aliphatic and aromatic mono- and polycarbonates. The resulting carbonates are useful in a wide variety of applications, especially polycarbon-ates which can be molded or formed into films, sheets, fibers, laminates, or reinforced plastics by conventional techniques. |
