Process for the production of 4-amino-3,5-dichlorobenzotrifluoride with high purity commercial products being obtained in parallel

Process for the production of 4-amino-3,5-dichlorobenzotrifluoride comprising the stages:A) chlorination of 4-chlorobenzotrichloride, in the presence of a Lewis acid, in order to obtain a mixture of 3,4-dichlorobenzotrichloride and 3,4,5-trichlorobenzotrichloride and other chlorine derivatives by performing the reaction in such a manner as to obtain in the mixture of reaction products a quantity of 3,4,5-trichlorobenzotrichloride of greater than 10% by weight and preferably of between 20% and 30% by weight and a concentration of 3,4-trichlorobenzotrichloride of less than 90% by weight and preferably of between approx. 55% and 75% by weight, relative to the total weight of the chlorinated derivatives;B) fluorination with hydrofluoric acid of the mixture of chlorination products as obtained in stage A) in order to obtain the corresponding benzotrifluorides; andC) separation by distillation of the mixture of products of stage B) in order to obtain 3,4,5-trichlorobenzotrifluoride or an isomeric mixture of 3,4,5- and 2,4,5-trichlorobenzotrifluoride; andD) amination of 3,4,5-trichlorobenzotrifluoride or of said isomeric mixture.
