Method for producing diaryl carbonates |
| abstract |
A process for the production of an aromatic carbonate is disclosed. Accordingly, an aromatic hydroxy compound is reacted with carbon monoxide and oxygen in the presence of a platinum group metal catalyst, a co-catalyst, a base, and optionally a quaternary salt as well as an inert organic solvent. The reaction is carried out under conditions whereby the inert organic solvent forms an azeotrope with the water arising during the reaction. The azeotrope is then removed from the reaction mixture. |
