Beschreibung
Zusammenfassung:	The invention relates to a method for producing a diaryl carbonate by reacting phosgene with molten monohydroxy aromatics in the presence of at least one catalyst and without adding an additional solvent. The invention is characterised in that the catalyst or catalysts from the recovery of the diaryl carbonate are fed back into the process.
