Abstract

Procedimiento para la obtención de solución acuosa de hidroxilamina, de gran pureza, mediante concentración y purificación de una solución acuosa de hidroxilamina, caracterizado porque la concentración se lleva a cabo en una columna, se retiran vahos, que contienen hidroxilamina, a través de una salida lateral en la cola de la columna y se obtiene hidroxilamina de gran pureza mediante condensación a partir de los vahos.
