Abstract

PROCEDIMIENTO PARA LA RECUPERACION EN CONTINUO DE ACETONITRILO MUY PURO A PARTIR DE ACETONITRILO BRUTO QUE CONTIENE ACETONITRILO, AGUA, CIANURO DE HIDROGENO Y COMPUESTOS ORGANICOS PESADOS. CONSISTE EN UNA PRIMERA DESTILACION DE LA MEZCLA A LA PRESION ATMOSFERICA, RETIRANDO HCN; SE FORMA UN PRODUCTO DE COLAS QUE CONTIENE AGUA Y UN AZEOTROPO DE ACETONITRILO/AGUA. DESTILACION DE ESTE AZEOTROPO A PRESION INFERIOR A LA ATMOSFERICA, CON LO QUE SE FORMA OTRO PRODUCTO DE COLAS Y UN SEGUNDO AZEOTROPO ACETONITRILO/AGUA MAS RICO EN ACETONITRILO. DESTILACION DEL SEGUNDO AZEOTROPO A UNA PRESION SUPERIOR A UNA ATMOSFERA, CON LO QUE SE OBTIENE UN AZEOTROPO QUE CONTIENE TODO EL AGUA, UN PRODUCTO DE COLAS CONSTITUIDO FUNDAMENTALMENTE POR ACETONITRILO Y COMPUESTOS ORGANICOS PESADOS, Y UNA CORRIENTE LATERAL DE ACETONITRILO DE ELEVADA PUREZA. TIENE APLICACION PARA EL TRATAMIENTO DE MEZCLAS OBTENIDAS POR AMOXIDACION DE PROPILENO CON OXIGENO Y AMONIACO PARA FORMAR ACRILONITRILO.
