Paragraph 0038-0049, (2021/11/26)
In the presence of a catalyst, mesitylene is used as a raw material, chlorine is introduced for chlorination reaction to obtain mesialose, and the catalyst is azobisisobutyronitrile. The preparation process is simple, the conversion rate is high, the prep
METHOD FOR THE PREPARATION OF TRICHLOROMETHYL-GROUP-SUBSTITUTED BENZENE
-
Paragraph 0158, (2016/06/28)
The present application relates to a method for photochlorination, and specifically to photochlorination by a photochemical reaction of an aromatic compound with gaseous chlorine so as to prepare a trichloromethyl-substituted benzene, and to a method using bis-(trichloromethyl)-benzene as the trichloromethyl-substituted benzene to prepare by further reaction bis-(chloroformyl)-benzene. Through the control of temperature, illuminance and consumption of gaseous chlorine, the method of this application can greatly improve the purity of trichloromethyl-substituted benzene and further prepare polymer-grade bis-(chloroformyl)-benzene with low cost. The present application also relates to a method for purifying trichloromethyl-substituted benzene, and specifically to a method for purifying trichloromethyl-substituted benzene via molecular distillation. The present application further relates to a photochlorination reactor for use in photochlorination reactions (such as those of the present application).
