| titleOfInvention | Process for the preparation of phenyl carbonates or polycarbonates |
| abstract | A process for the preparation of an aromatic carbonate or polycarbonate from a phenol or bisphenol, methanol, carbon monoxide and oxygen comprising the steps of 1) reacting phenol or bisphenol with acetic anhydride to form (bis)phenyl acetate; 2) reacting dimethyl carbonate with (bis)phenyl acetate from step 1 to produce a phenyl carbonate or polycarbonate and methyl acetate; and 3) reacting the methyl acetate with carbon monoxide to produce acetic anhydride for use in step 1. In a desirable embodiment the dimethyl carbonate may also be prepared by reaction of methanol, carbon monoxide and oxygen. |
