Abstract

LA PRESENTE INVENCION DESCRIBE UN PROCESO PARA LA PURIFICACION Y CRISTALIZACION DE YODAMIDOL, EN DONDE 1-PROPANOL, O 2-PROPANOL, SE AÑADE A UNA DISOLUCION ACUOSA DE YOPAMIDOL SEGUIDO, SI ES NECESARIO, POR UNA DESTILACION AZEOTROPICA PARA REDUCIR LA CANTIDAD DE AGUA EN RELACION A LA CANTIDAD DE PROPANOL, Y POR LA CUAL SE ASEGURA UNA PRODUCCION ELEVADA. LA DISOLUCION ACUOSA PUEDE SER PREPARADA POR LA DISOLUCION DE YOPAMIDOL CRUDO EN AGUA O DIRECTAMENTE A PARTIR DE LA REACCION EN LA QUE SE FORMA EL YOPAMIDOL. LA PRESENTE INVENCION PRESENTA VENTAJAS PARA LA PRODUCCION ORDINARIA DE YOPAMIDOL DESDE QUE LA CRISTALIZACION ES SENCILLA DE REALIZAR, REPRODUCTIBLE EN UNA ESCALA INDUSTRIALES.
