Abstract

EL CARBONATO DE DIMETILO SE PREPARA POR MEDIO DE UN PROCESO CONTINUO: * INTRODUCIENDO, EN UNA CAMARA DE REACCION, MONOXIDO DE CARBONO Y OXIGENO, PARA UNA MEZCLA DE REACCION LIQUIDA CON UN VOLUMEN Y UNA COMPOSICION EN GRAN MEDIDA CONSTANTES, CONTENIENDO METANOL, CARBONATO DE DIMETILO, AGUA, Y UN CATALIZADOR DE COBRE; * VAPORIZANDO DE LA MEZCLA DE REACCION UNA CORRIENTE DE METANOL, AGUA Y CARBONATO DE DIMETILO, QUE SE DESARROLLA JUNTO CON LA CORRIENTE GASEOSA QUE CONTIENE MONOXIDO DE CARBONO; Y * RECUPERANDO AGUA Y CARBONATO DE DIMETILO DE DICHA MEZCLA VAPORIZADA, EN CANTIDADES IGUALES, EN GRAN MEDIDA, A LAS RESPECTIVAS CANTIDADES DEL MISMO QUE SE FORMAN EN LA CAMARA DE REACCION Y RECICLANDO LOS DEMAS COMPONENTES. ESTE PROCESO, QUE SE CARACTERIZA FUNDAMENTALMENTE POR QUE EN LA MEZCLA DE REACCION LIQUIDA SE MANTIENEN UNA CONCENTRACION DE METANOL Y AGUA QUE SON RESPECTIVAMENTE IGUALES O SUPERIORES AL 30% POR PESO, Y IGUALES O INFERIORES AL 10% POR PESO, HACE POSIBLE OBTENER EL CARBONATO DE DIMETILO CON UNA PRODUCTIVIDAD MEJORADA.
