Abstract

METODO DE REDUCCION DEL CONTENIDO EN CARBONATO DE ETILENO EN ETILENGLICOL OBTENIDO MEDIANTE HIDROLISIS DE CARBONATO DE ETILENO EN PRESENCIA DE UN CATALIZADOR. COMPRENDE LA DESTILACION EN UN DISPOSITIVO DE CONTACTO VAPOR-LIQUIDO, EL EFLUYENTE DE LA HIDROLISIS DE CRBONATO DE ETILENO, QUE CONTIENE ETILENGLICOL, GLICOLES SUPERIORES, CATALIZADOR Y CARBONATO DE ETILENO SIN REACCIONAR; SEPARACION DE UNA FRACCION DE MENOR PUNTO DE EBULLICION QUE CONTIENE FUNDAMENTALMENTE ETILENGLICOL Y AGUA, Y UNA FRACCION LIQUIDA DE MAYOR PUNTO DE EBULLICION, CONSTITUIDA FUNDAMENTALMENTE POR CATALIZADOR, ETILENGLICOL Y GLICOLES SUPERIORES; RECIRCULAR UNA PARTE DE LA FRACCION DE PUNTO DE EBULLICION ALTO COMOREFLUJO CONTRA LA FRACCION DE MENOR PUNTO DE EBULLICION; Y RECICLAR LA PARTE RESTANTE A LA REACCION DE HIDROLISIS. ESTE ETILENGLICOL TIENE APLICACIONES PARA LA FABRICACION DE FIBRAS.
