Description

Micro-reactor

Technical Field

The utility model belongs to the technical field of the chemical machinery technique and specifically relates to a micro-reactor.

Background

The micro-reactor is a micro-channel type reactor established on a continuous flow basis and is used for replacing the traditional batch reactors such as glass flasks and funnels, reaction kettles commonly used in industrial organic synthesis and the like. The micro-reactor has a large number of micro-reaction channels which are manufactured by precise processing technology, and the micro-reaction channels can provide extremely large surface area and have extremely high heat transfer efficiency. In addition, the microreactor operates continuously instead of intermittently, making it possible to control the residence time of the reactants accurately. These characteristics allow the organic synthesis reaction to be precisely controlled on a microscopic scale, and provide possibility for improving reaction selectivity and operation safety.

Most of the microreactor reaction channels used at present have simple structures, and the reaction products can not be fully mixed and reacted due to common mixing effect, so that the yield of the reaction products is not high.
