A PROCESS FOR PREPARING A DIARYL CARBONATE FROM A DIARYL OXALATE IN A LIQUID PHASE BY THE DECARBONYLATION IS CONDUCTED BY THE STEPS OF1) PERFORMING A DECARBONYLATION REACTION OF A DIARYL OXALATE IN THE PRESENCE OF AN ORGANIC PHOSPHORUS COMPOUND CATALYST TO GIVE A REACTION MIXTURE OF A DIARYL CARBONATE AND THE ORGANIC PHOSPHORUS COMPOUND CATALYST;2) RECOVERING THE DIARYL CARBONATE FROM THE REACTION MIXTURE; AN3) PERFORMING A DECARBONYLATION REACTION OF A DIARYL OXALATE IN THE PRESENCE OF THE REACTION MIXTURE FROM WHICH THE DIARYL CARBONATE HAS BEEN RECOVERED AND TO WHICH A HALOGEN ATOM-CONTAINING COMPOUND IS ADDED, TO GIVE A REACTION MIXTURE OF A DIARYL CARBONATE AND THE ORGANIC PHOSPHORUS COMPOUND CATALYST.
