摘要： Diphenyl carbonate is produced by reacting phenol with diethyl carbonate in a series of fixed bed reactors each of which is connected at different position on a distillation column via side draw and return streams. The composition of material in a distillation column varies along the length of the column, which is predictable under a given set of conditions of temperature and pressure, thus withdrawing streams at different stages in the column, allows the reactor receiving the feed from a particular stage to be operated under conditions to maximize the desired reaction, while allowing the unreacted or byproduct to go back into the distillation and be sent to a stage (by the equilibrium of the distillation) where they are favorably treated in a reactor.

摘要： The invention aims at providing a specific apparatus and process by which a low-boiling reaction mixture that is produced by a reaction-distillation process of continuously feeding a raw material consisting of a cyclic carbonate and an aliphatic monohydric alcohol into a continuous multi-stage distillation column holding a homogeneous catalyst therein to conduct reaction and distillation simultaneously and that comprises a large amount of a dialkyl carbonate and the aliphatic monohydric alcohol can be separated into an overhead component (B T ) containing the aliphatic monohydric alcohol as the main component and a bottom component (B B ) containing the dialkyl carbonate as the main component by distillation in a one distillation column industrially and stably over a long term. It has been found that between dialkyl carbonate and diol produced by the reaction-distillation process, the dialkyl carbonate can be separated as high-purity one having a purity of 97% or above through distillation stably on an industrial scale of at least two tons per hour over a long term of 1000 hours or longer and in a high yield by using one continuous multi-stage distillation column having a specific structure.
