Abstract

Procedimiento para deshalogenar aminas aromáticas halogenadas que conduce a la obtención preferente de derivados que llevan menor número de átomos de halógeno, al menos uno de los cuales está situado en posición meta respecto a la agrupación amino, en fase vapor, por acción de hidrógeno en presencia de un catalizador de hidrogenación de acción acondicionada, a una temperatura comprendidas entre 280 y 420ºC, caracterizado porque la fase activa del catalizador contiene, además del metal catalizador principal, una cantidad secundaria de un catalizador auxiliar de hidrogenación constituido por otro metal diferente del primero.
