| titleOfInvention | PROCEDURE FOR THE ELABORATION OF REACTION MIXTURES CONTAINING DIARILO CARBONATE. |
| abstract | Process for the preparation of reaction mixtures from the manufacture of diaryl carbonate by direct carbonylation of aromatic hydroxy compounds, characterized in that an adduct of diaryl carbonate and aromatic hydroxy compound crystallizes from a reaction mixture containing diaryl carbonate , aromatic hydroxy compound, water, base and quaternary salt, from the liquid phase it is eliminated, at pressures from 10 to 200 mbar and at temperatures from 40 to 160 ° C, at least 0.2% by weight, based on the mixture of the reaction before crystallization, of a distillate containing the aromatic hydroxy compound, and the liquid phase is conducted again to the stage of the direct carbonylation reaction without further elaboration. |
