Abstract

SE DESCRIBE UN PROCESO CONTINUO PARA PREPARAR CARBONATO DE DIMETILO QUE COMPRENDE: UN PRIMER PASO DE INTRODUCCION DE UN GAS QUE CONTIENE MONOXIDO DE CARBONO Y NITRITO DE METILO EN UN REACTOR LLENO DE UN CATALIZADOR SOLIDO PARA OBTENER UN PRODUCTO DE REACCION QUE CONTIENE CARBONATO DE DIMETILO; UN SEGUNDO PASO DE SEPARACION DEL PRODUCTO DE REACCION EN UN GAS NO CONDENSADO Y UNA SOLUCION QUE CONTIENE CARBONATO DE DIMETILO AÑADIENDO OXALATO DE DIMETILO; UN TERCER PASO DE INTRODUCCION DEL GAS NO CONDENSADO EN UNA COLUMNA DE REGENERACION PARA PONERLO EN CONTACTO CON UN GAS QUE CONTIENE OXIGENO EN ESTADO MOLECULAR Y METANOL, REGENERANDO ASI EL MONOXIDO DE CARBONO EN NITRITO DE METILO PARA QUE CONTENGA DEL 2 AL 7% POR VOLUMEN DE MONOXIDO DE NITROGENO EN UN GAS NO ABSORBIDO EN UNA SALIDA DE LA COLUMNA QUE, A SU VEZ, SE INTRODUCE EN EL REACTOR DEL PRIMER PASO; UN CUARTO PASO DE EXTRACCION, DESTILACION Y SEPARACION DEL CARBONATO DE DIMETILO DE LA SOLUCION AÑADIENDO MAS OXALATO DE DIMETILO PARA EXTRAER EL METANOL; Y UN QUINTO PASO DE DESTILACION Y SEPARACION DEL CARBONATO DE DIMENTILO A PARTIR DE LA SOLUCION MEZCLADA PARA EXTRAER EL OXALATO DE DIMENTILO Y RECICLADO DEL OXALATO DE DIMETILO EXTRAIDO AL CUARTO PASO.
