(EN) A NOVEL PROCESS FOR PREPARING 2, 6-DICHLORO-4-TRIFLUOROMETHYL-ANILINE USING AMMONIA
Abrégé
(EN) The invention relates to a method preparing polyhalogented p-trifluoromethylanilines, particularly useful as a reaction intermediate for preparing agrochemicals. The products of the invention method are obtained by the action of ammonia on 3,4-dihalobenzotrifluoride at a temperature ranging between 200°C to 300°C. The reaction is carried out in the presence of an alkali halide. The resultant intermediate is halogenated with halogenating agents like sulfuryl chloride, chlorine and PCl5 to get 2,6-dihalo-p-trifluoromethylaniline.
