To provide an industrially advantageous method for producing a dialkyl carbonate by subjecting an alkylene carbonate and an alcohol to transesterification.

The method for producing the dialkyl carbonate comprises subjecting the alkylene carbonate and the alcohol to the transesterification. In the method, an alumina-supported potassium fluoride is used as a catalyst. Since the catalyst has a low solubility in a reactional solution in the heterogeneous system, the efficiency of a purification step is improved and the objective substance can extremely advantageously be produced.
