Abstract

PROCESSO PARA PREPARAçãO DE PERALO ALQUIL ANILINA POLIHALOGENADA. A invenção se refere a um processo para a preparação de trifluorometilanilinas polihalogenadas principalmente úteis como um intermediário de reação para preparação de agroquímicos. Os produtos do método inventivo são obtidos pela ação da amónia em 3,4 dialobenzotrifluoreto a uma temperatura que varia entre 200<198>C a 300<198>C. A reação é realizada na presença de um composto alcalino. O intermediário obtido é halogenado com agentes halogenantes como o cloreto de sulfurilo, cloro e PCL~5~ para obter 2,6-dialo-p-trifluorometilanilina.PROCESS FOR PREPARATION OF POLYHALOGENED ANILINE ALKAL PERAL. The invention relates to a process for the preparation of polyhalogenated trifluoromethylanilines primarily useful as a reaction intermediate for the preparation of agrochemicals. The products of the inventive method are obtained by the action of ammonia on 3,4 dialobenzotrifluoride at a temperature ranging from 200 ° C to 300 ° C. The reaction is performed in the presence of an alkaline compound. The obtained intermediate is halogenated with halogenating agents such as sulfuryl chloride, chlorine and PCL-5 to obtain 2,6-dialo-p-trifluoromethylaniline.
