Method of producing polycarbonate |
| abstract |
The present invention is a combined process for preparing polycarbonates from bisphenols and diaryl carbonates, wherein the free monophenols are reacted again for the production of diaryl carbonates and formed in the production of the diaryl carbonates. Alkali metal halides are converted to chlorine and alkali hydroxide solutions by electrochemical oxidation, optionally on gas diffusion electrodes, the chlorine is recycled to the preparation of phosgene and the alkali hydroxide solution is made of diaryl carbonate. To a combined method for recycling. |
