Abstract: Obtencion de sales de hidroxilamonio por reduccion catalítica de monoxido de nitrogeno con hidrogeno en presencia de un catalizador de hidrogenacion, en cuyo procedimiento: (a) en una primera etapa se filtra la mezcla de reaccion obtenida después de la reaccion, obteniéndose una solucion que consta sustancialmente de sal de hidroxilamonio y un residuo de filtracion que contiene, substancialmente, una mezcla a partir de catalizador de hidrogenacion y una solucion a partir de, substancialmente, sal de hidroxilamonio, y (b) en una segunda etapa se somete el residuo de filtracion a la sedimentacion para el enriquecimiento del catalizador de hidrogenacion, obteniendose una mezcla que tiene un mayor contenido de catalizador de hidrogenacion, que el residuo de filtracion, y una mezcla que tiene un menor contenido de catalizador de hidrogenacion, que el residuo de filtracion.
