Abstract

The invention discloses a continuous segmented feeding reactor for synthesis reaction, which comprises a three-layer jacket structure, the outermost layer is a heat exchange medium layer, a heat exchange medium inlet and a heat exchange medium outlet are arranged on a heat exchange medium layer shell, and a guide plate is arranged between a reactant shell and a jacket shell. The guide plate is a spiral plate. The middle layer is a reaction material A feed section and a main reaction space, and is provided with a reaction material A feed inlet and a reaction product outlet. An innermost centerpipe is a reaction material B feed pipe. The outermost layer is a heat exchange medium channel, a heat exchange medium flows along the guide plate and exchanges heat through a pipe wall, and leaves the reactor through the heat exchange medium outlet after the heat exchange is completed. The continuous segmented feeding reactor can realize the continuous addition of reaction materials, realizes thecontinuous reaction, improves the yield, reduces the operation cost, strengthens the heat transfer effect and avoids the problem of side reactions caused by a large local temperature difference.

Description

Technical field [0001] The invention relates to the technical field of chemical reaction equipment, in particular to a continuous segmented feed reactor for synthesis reaction. Background technique [0002] At present, many chemical reactions are involved in the production process of pharmaceuticals and fine chemicals. Some chemical reactions involve multiple materials. During the reaction process, a large amount of reaction heat is absorbed or released, and the selectivity and conversion rate of the reaction process are affected by temperature conditions. It is larger, so the heat exchange and temperature control during the reaction process are very important to improve the reaction selectivity and conversion rate. [0003] The chemical synthesis reaction in the pharmaceutical and fine chemical production process is usually carried out in a tank reactor. The heat exchange is performed by setting a jacket on the synthesis tank. However, due to the small heat exchange area, the mass...
