| titleOfInvention | Method for synthesizing 2-chloro-5-nitrobenzoic acid through microchannel reactor |
| abstract | The invention provides a method for synthesizing 2-chloro-5-nitrobenzoic acid through a microchannel reactor. The method comprises the steps of dissolving a raw material o-chlorobenzoic acid into concentrated sulfuric acid to obtain a material 1, and entering a preheating module; adopting fuming nitric acid and the concentrated sulfuric acid as a material 2 and a material 3, and entering another preheating module; preheating the material 1, the material 2 and the material 3, entering a reaction module group for reacting, collecting effluent reaction liquid, processing to obtain a crude product, and refining to obtain the product 2-chloro-5-nitrobenzoic acid. According to the method provided by the invention, the reaction time is shortened to a few minutes to a few seconds, the production energy consumption is reduced, and the reaction efficiency is remarkably improved. High-efficient mass and heat transfer efficiency ensures the reaction temperature to maintain within a setting range, the possibilities of temperature out of control, temperature runaway and even sharp reaction overflow or explosion caused by over-high local concentration do not exist, the intrinsic safety problem of the nitration reaction is solved fundamentally, and the reaction yield and the product purity are remarkably improved. |
