基丙烯酸异丁酯 - Reference Information

uses

chloroanilines are an important class of pesticides, pharmaceutical intermediates, widely used in medicine, dyes, synthesis of fine chemical products such as pigments, 2-bromo-4, 6-dichloroaniline for the synthesis of Diptera, rivalon, dipyrone and azo dyes.

preparation

add 2, 4-dichloroaniline into the reaction kettle, turn on the irradiation light source, under the condition of light, pure bromine is added dropwise, the reaction temperature, reaction rate and other indicators are well controlled, and 2-bromo-4, 6-dichloroaniline is generated by light bromination reaction, followed by crystallization, after filtration, centrifugation and drying, the final target product 2-bromo-4, 6-dichloroaniline was formed.
