| titleOfInvention | PROCEDURE FOR THE MANUFACTURE OF DIARIL CARBONATE. |
| abstract | Process for the manufacture of diaryl carbonate and processing of at least a part of the solution containing alkali chloride resulting in this respect in a subsequent alkali chloride electrolysis, comprising the following steps: a) phosgene manufacturing by reaction of chlorine with carbon monoxide, b) reaction of the phosgene formed according to step a) with at least one monophenol in the presence of a base and, if necessary, a basic catalyst to a diaryl carbonate and a solution containing alkali chloride, c) separation and processing of the diaryl carbonate formed in step b), d) separation of the solution containing the remaining alkali chloride according to step c) of the solvent residues and, where appropriate, catalyst residues, particularly by entrainment of the vapor solution of water, and treatment with adsorbents, particularly with activated carbon, e) electrochemical oxidation of at least a part of the solution containing alkaline chloride of d) with chlorine formation, alkaline bleach and, in the case of hydrogen, characterized in that in the separation d) of the solution before treatment with adsorbents, the solution is adjusted to a pH value less than or equal to at 8 and f) at least a part of the chlorine manufactured according to stage e) is recycled to the manufacture of phosgene according to stage a) and / or g) at least a part of the alkaline lye manufactured according to stage e) is recycled to the manufacture of diaryl carbonate according to step b). |
