The utility model belongs to the technical field of the chemical industry, concretely relates to 1, 3-diamino-2-hydroxypropane continuous production system, this system include material reaction subsystem, ammonia distillation subsystem, film evaporation subsystem, receive material subsystem, vacuum subsystem and ammonia absorption subsystem. The utility model adopts continuous feeding and continuous reaction, reduces the reaction time, greatly reduces the labor intensity, stabilizes the quality of 1, 3-diamino-2-hydroxypropane, improves the yield, and reduces the energy consumption and the product cost. |
