摘要: This invention is involved with a preparation method of 2,6-dichlor-4-trifluoromethyl aniline. With this process, 4-chlorotrifluoromethyl benzene is used as the starting material and subjected to halogenation reaction and ammoniation reaction and through separation of reaction products the desired 2,6-dichlor-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.
