Process for the preparation of diaryl carbonates |
| abstract |
The invention relates to a process for the preparation of an aromatic carbonate by oxidative carbonylation of an aromatic hydroxy compound with carbon monoxide and oxygen in the presence of a platinum metal catalyst, a cocatalyst, a base and optionally a quaternary salt and an inert organic solvent, the inert organic solvent being among the Reaction conditions forms an azeotrope with the water formed in the reaction, and this azeotrope is removed from the reaction mixture. |
