Preparation method of 2, 6-dichlor-4-trifluoromethyl aniline
This invention is involved with a preparation method of 2,6-dichloro-4-trifluoromethyl-aniline. With this process, p-Chlorobenzotrifluoride is used as the starting material and subjected to halogenation reaction and ammoniation reaction and through separation of reaction products the desired 2,6-dichloro-4-trifluoromethyl-aniline is obtained. In addition, ammonia is recovered from the surplus ammonia water in ammoniation reaction. This applied invention in characterized by simple process, cheap and easy-available raw materials, high reaction yield and friendly environment.
