    • An aromatic carbonate ester is continuously and efficiently prepared by the transesterification of an aromatic carboxylate with an aliphatic carbonate ester and/or aromatic.aliphatic carbonate ester. A raw material including an aromatic carboxylate, aliphatic carbonate ester and/or aromatic.aliphatic carbonate ester, and a catalyst are continuously fed to a first stage of a reactive distillation column (1) through a raw material feeding pipe (5). Meanwhile, an aliphatic carbonate ester (a) whose boiling point is lower than that of a reactant liquid that is present in a second stage lower than the first stage is continuously fed to the second stage through an aliphatic carbonate ester (a) feeding pipe (6). The second stage is preferably a column bottom section of the reactive distillation column (1). The amount of aliphatic carbonate ester (a) fed is preferably 0.001 to 5 times, by weight, more than the amount of the raw material fed.
