摘要： An aromatic carbonic ester is prepared continuously and efficiently by reacting an aromatic carboxylic ester with an aliphatic carbonic ester and/or an aromatic/aliphatic carbonic ester through transesterification. A raw material comprising an aromatic carboxylic ester and an aliphatic or aromatic/aliphatic carbonic ester and a catalyst are continuously fed into the first stage of a reaction-distillation column (1) through a feed pipe (5), while an aliphatic carbonic ester (a) having a boiling point lower than that of the reaction fluid present in the second stage under the above first stage is continuously fed into the second stage through a feed pipe (6). The second plate is preferably the bottom of the reaction-distillation column (1). The feed of the aliphatic carbonic ester (a) is preferably 0.001 to 5 times that of the raw material by weight.

摘要： A reaction distillation apparatus which can be applied to a relatively complicated reaction comprising the combination of two or more stages of equilibrium reactions, and a reaction distillation method which can efficiently conduct this reaction. Raw material feed pipes (5, 6 and 7) are connected to a reaction distillation column (1). These raw material feed pipes (5, 6 and 7) are sequentially disposed at mutually different stages from the column top. More preferably, the reaction distillation column (1) is equipped with stages not having a raw material feed pipe connected thereto, between the first stage at which the raw material feed pipe (5) is connected and the second stage at which the raw material feed pipe (6) is connected, and between the second stage and the third stage at which the raw material feed pipe (7) is connected. The raw material (A) is supplied from the raw material feed pipe (5), the raw material (B) is supplied from the raw material feed pipe (6) and the raw material (E) is supplied from the raw material feed pipe (7). In this way, the raw materials (A) and (B) are brought into the gas-liquid contact while the product (C) and the raw material (E) are brought into the gas-liquid contact.
