Abstract:
A reactive distillation method for performing a reaction composed of at least two equilibrium reactions using a reactive distillation equipment having not less than three stages, comprising at least the steps of:performing a first equilibrium reaction between two kinds of raw materials by feeding a raw material (a first raw material) having a higher boiling point between the two kinds of raw material to a first stage and feeding the other raw material (a second raw material) having a lower boiling point to a second stage lower than the first stage: andperforming a second equilibrium reaction between a third raw material and a product having a boiling point higher than the first and second raw materials between products produced by the first equilibrium reaction by feeding the third material to a third stage lower than the second stage.
