Reaction distilling apparatus

Abstract

The invention relates to reaction distillation equipment. It includes reaction chamber and distillation chamber, and reaction is on the top of distillation chamber. There is a feed inlet on the upside of reaction chamber and condensation circumfluence equipment on top. There is a column plate or filling in distillation chamber and discharge gate in bottom. A pipe connects the top of reaction chamber with the top of distillation. A pipe in inverted U shape connects the bottom of reaction with the top of distillation. Horizontal height at connection of pipe and reaction chamber is higher than connection of pipe and distillation chamber. Top of the pipe is over reaction chamber for one third of height and below entrance or exit. The reaction distillation equipment effectively solves the problem that reaction production is removed in time in liquid phase chemical reaction which boiling point of reaction production is higher than other materials. Adopting the invention, highly pure reaction production can be obtained simultaneously.

Description

technical field [0001] The invention relates to a reaction distillation device used for liquid phase reaction in the chemical industry field. Background technique [0002] For most chemical reactions, it is always beneficial for the reaction to remove the reaction product from the reaction system in time. For reversible reactions, timely removal of reaction products is conducive to the positive direction of the reaction, and for compound reaction systems with series and parallel reactions, timely removal of reaction products is conducive to the reduction of by-products. When the boiling point of the product is lower than other materials in the reaction system (including reactants, solvents, etc.), it is more convenient to remove the reaction product from the reaction system. There are very mature reactive distillation or reactive distillation devices in the prior art . This device includes two parts: reaction and distillation or rectification. As long as the reaction is co...

AI Technical Summary

Problems solved by technology

However, if the boiling point of the reaction product is higher than that of other materials in the reaction system, it is difficult to remove the reaction product from the reaction system in time. The traditional method can only enter the reaction materials containing the reaction product into distillation or refining after the reaction. Distillation system for separation, which will inevitably lead to a reduction in reaction conversion or selectivity
