Abstract:

The hydrogenation reaction is a type of reaction which is very common in organic synthesis. The conventional batch hydrogenation reactor has the problems of low reaction efficiency, cumbersome operation and poor safety. The method of heterogeneous hydrogenation in a continuous microreactor can provide higher mass transfer performance, easy recycling of the catalyst and the purification of the product are more convenient, which can greatly improve the production efficiency and reduce the loss of precious metal catalysts. With these advantages, continuous hydrogenation technology in microreactors has received more and more attention. The research progress of commonly used microreactors and solid metal catalyst types, as well as heterogeneous high-efficiency catalytic hydrogenation of different functional groups in continuous microreactor are described in this paper. On this basis, the application of this technology in the field of fine chemicals is prospected. The continuous microreactor technology enables the hydrogenation process under safer, more efficient and more environmentally friendly conditions. It has high industrial application value and is one of the key development directions in the chemical industry in the future.
