2-Bromo-4,6-dichloroaniline is used to synthesize propanil, dimethoate, mefenamic acid and azo dyes.
Take 2,4-dichloroaniline and add it into the reaction kettle, turn on the irradiation light source, add pure bromine dropwise under the light condition, do a good job of controlling the reaction temperature, reaction rate and other indexes, and generate 2-bromo-4,6-dichloroaniline through photobromination, and then generate 2-bromo-4,6-dichloroaniline, which is the final target product, after sequentially going through the crystallization, filtration, centrifugation, and drying process.
