Abstract

La presente invención se refiere a un metodo para producir ácido 5-amino salicílico con ácido sulfanílico como producto químico auxiliar, caracterizado en que el ácido 5-(p-sulfofenil azo) salicílico, producido mediante enlace de la sal de sodio doble del ácido salicílico con una sal de diazonio de ácido sulfanílico, se divide mediante hidrogenación con gas de hidrógeno y un catalizador a presión y temperatura elevadas en exceso de 50 grados C, despues de lo cual el ácido 5-amino salicílico obtenido de esta manera se precipita del licor madre mediante acidificación del mismo.
