2-Chloro-5-chloromethylpyridine is an intermediate of the technical imidacloprid. Since the production involves processes such as cracking, chlorination, addition, and cyclization, multiple sets of equipment are amplified in parallel, occupying a lot of production resources. With the deeply research and development of Zhongshan Zhi'an microreactor equipment, the silicon carbide microreactor production line can solve the corrosion of materials and greatly reduce the production cost. The comprehensive performance is as follows: firstly, the total investment cost of the project is reduced by 15-20%. Secondly, the plant, public works, land occupation and manpower input are reduced by at least 60%. Thirdly, realized the movement operation and automatic control through digitization. Fourthly, reliance on technicians and operators will be minimized.
