Abstract: A process for the preparation of an aromatic carbonate is disclosed. The process entails reacting in the presence of a catalyst system an aromatic hydroxy compound with carbon monoxide and oxygen, and optionally in one or more solvents to produce a liquid phase. At least a portion of the liquid phase is subjected to a treatment to obtain a treated liquid phase. The treatment entails at least one of (a) heating to a temperature that is at most mean reaction temperature without passing oxygen thereto, and (b) adding one or more protic compounds thereto, and (c) passing through it one or more inert or reducing gases. Solid metallic catalyst constituents are then separated from the treated liquid phase.
