Abstract
SE PRESENTA UN PROCESO MEJORADO PARA LA SEPARACION DE ACETONA DE UN SISTEMA DE PRODUCCION EN DONDE SE PRODUCE ANHIDRIDO ACETICO A BASE DE PONER EN CONTACTO UNA MEZCLA QUE CONTIENE YODURO DE METILO Y ACETATO DE METILO Y/O ETER DIMETILICO CON MONOXIDO DE CARBONO ANTE LA PRESENCIA DE UN CATALIZADOR DE CARBONILACION O UN SISTEMA CATALIZADOR. EL PROCESO CONSISTE EN UN PASO DE EXTRACCION DEL YODURO DE METILO Y AGUA EN DONDE LA ACETONA SE SEPARA DE UNA MEZCLA DE ACETATO DE METILO, YODURO DE METILO Y ACETONA.
