Zusammenfassung:	PURPOSE:To provide a method for advantageously producing a carbonic acid ester by reacting carbon dioxide with a carbonic acid orthoester in synthesizing the carbonic acid ester. CONSTITUTION:The characteristic of this method for producing a carbonic acid ester comprises reacting carbon dioxide with a carbonic acid orthoester in the presence of a catalyst of a quaternary ammonium salt or the quaternary ammonium salt and a Broensted acid in combination.
