ABSTRACT:
In the process for preparing an aromatic carbonate from an aromatic hydroxy compound, CO and O.sub.2 in the presence of a quaternary salt and a base, use is advantageously made of supported catalysts which, in the reaction-ready state, contain a platinum metal, a platinum metal compound or a complex containing a platinum metal compound on a support comprising a metal oxide whose metal can occur in a plurality of oxidation states.
