Abstract

LA INVENCION SE DIRIGE A UN PROCESO PARA LA ELABORACION DE 2 VINIL - 1,3 - DIOXOLANO MEDIANTE TRANSFORMACION DE ACROLEINA CON UN ETILENGLICOL EN PRESENCIA DE UN CATALIZADOR ACIDO SOLIDO Y TRATAMIENTO DE LA MEZCLA DE REACCION. LA SELECTIVIDAD SE ELEVA EN CONTRA DE LOS PROCESOS CONOCIDOS, DONDE LA TRANSFORMACION SE REALIZA EN PRESENCIA DE UN CATALIZADOR ACIDO SOLIDO EN UNA TEMPERATURA POR DEBAJO DE 50 TRAE LA MEZCLA DE REACCION LIBERADA DEL CATALIZADOR BAJO UTILIZACION DE UN ETILENGLICOL EN PRESENCIA DE DISOLVENTES ORGANICOS NO DISUELTOS CON UN PUNTO DE EBULLICION POR ENCIMA DE 130 DONDE LA EXTRACCION OBTENIDA EN AMBAS FASES SE TRATA DE FORMA DESTILATIVA Y LOS PRODUCTOS OBTENIDOS DE NUEVO Y EL DISOLVENTE ORGANICO SE RECICLAN.
