Zusammenfassung: | The invention provides a whole-process continuous green and environment-friendly production process of bromotriazine, and relates to the technical field of chemical synthesis, the process comprises the procedures of bromination, decoloration, extraction, condensation, alkali washing, acid washing, water washing, drying and packaging; a continuous flow microchannel reactor, a rotating disc type extraction tower and a dynamic tubular reactor are adopted for continuous production to replace an intermittent reaction kettle, continuous feeding and continuous discharging can be achieved, in the condensation process, cyanuric chloride is firstly dispersed into dichloromethane, the mass ratio of cyanuric chloride to dichloromethane is 1: (1-5), the mass ratio of cyanuric chloride to dichloromethane is 1: (1-5), and the mass ratio of cyanuric chloride to dichloromethane is 1: (1-5). The pollution of cyanuric chloride powder feeding to the environment and the harm to personnel are reduced, the effective conversion rate |
