Abstract

Procedimiento de deshalogenación de aminas halogenadas, aminadas o nitradas, que conduce a la obtención preferente de derivados que llevan menor número de átomos de halógenos, al menos uno de los cuales está sustituido en posición meta en relación al grupo amino, en fase vapor, por acción, a una temperatura comprendida entre 280 y 420ºC, de hidrógeno en presencia de un catalizador de hidrogenación de acción acondicionada, depositado sobre un soporte a base de alúmina, caracterizado porque se utiliza un soporte modificado al menos en superficie, por incorporación de un metal en forma de una sal o de un óxido, comprendiendo esta incorporación un tratamiento del soporte con dichos sal u óxido metálico, seguido por una calcinación a una temperatura que va aproximadamente de 500 a 1000ºC.
