| titleOfInvention | A kind of continuous synthesis method of isobutyryl chloride |
| abstract | The invention discloses a continuous synthesis method of isobutyryl chloride. It includes the following steps: in a continuous flow reactor, under the action of an amide catalyst, isobutyric acid and thionyl chloride are subjected to the acid chlorination reaction shown below; the temperature of the acid chlorination reaction is 50-160° C. ; The pressure of acid chlorination reaction is 2～15bar; The time of acid chlorination reaction is 20～300s. The invention overcomes the defect of poor mass transfer and heat transfer performance of the kettle type reactor, the reaction can run smoothly, the reaction time is greatly shortened, the energy consumption is reduced, and the cost is saved; the operation steps are few, the operation is simple, and the stability is high; The liquid volume is small, which can effectively avoid the generation of hot spots in the exothermic reaction, and substantially improve the safety of the process; high conversion rate, high selectivity, few side reactions, no other impurities in the crude product, high yield, post-processing Simple, easy to separate, no amplification effect, no wastewater treatment and environmental pollution problems. |
