The invention discloses a method for synthesizing liquid sodium carbamazepine in a microchannel reactor, comprising the following steps: preparing materials: pouring carbon disulfide, dimethylamine solution, sodium hydroxide solution and process water into respective measuring tanks; The volume flow of the raw material, while turning on the raw material metering pump, the carbon disulfide, dimethylamine solution, and sodium hydroxide solution from their respective metering tanks and simultaneously into the raw material static mixer and then into the microchannel reactor material inlet for reaction; concentration adjustment: Add process water to adjust product concentration and take samples for analysis. The present invention aims at the problems of long reaction time existing in the existing production process of sodium formate, difficult content control, requiring multiple analysis and detection, multiple water allocation, difficult safety control during operation, poor working environment and the like. chemical production process. Using a microchannel continuous flow reactor, the reaction time is shortened and the reaction efficiency is significantly improved. The reaction material is completely converted and the product yield is high. |
