Abstract

PROCEDIMIENTO CICLICO PARA LA PREPARACION DE UNA SOLUCION DE SAL DE HIDROXILAMONIO. CONSISTE EN MANTENER UN MEDIO DE REACCION ACIDO Y ACUOSO EN CIRCULACION ENTRE UNA ZONA DE SINTESIS DE SAL DE HIDROXILAMONIO Y UNA ZONA DE SINTESIS DE OXIMA. AL FLUIDO SE SUMINISTRA DE MANERA CONTINUA MONOXIDO DE NITROGENO, QUE ES CONVERTIDO EN HIDROXILAMINA MEDIANTE REDUCCION CATALICA CON HIDROGENO. EL LIQUIDO SE SOMETE ANTES DE QUE ENTRE A LA ZONA DE SINTESIS A UN PROCEDIMIENTO DE SEPARACION PONIENDO EL LIQUIDO EN INTERCAMBIO DE CALOR CON MONOXIDO DE NITROGENO QUE CONTIENE VAPOR DE AGUA. EL INTERCAMBIO TIENE LUGAR EN UNA SUPERFICIE SOBRE LA QUE SE CONDENSA VAPOR DE AGUA; EL GAS RESTANTE, QUE CONTIENE MONOXIDO DE NITROGENO, SE UTILIZA PARA LA OBTENCION DE HIDROXILAMINA.
