Abstract

LA INVENCION SE REFIERE A LA ELIMINACION DE CONTAMINANTES HIDROFOBOS Y DISOLVENTES ORGANICOS RESIDUALES A PARTIR DE IOHEXOL, MEDIANTE LA UTILIZACION DE UN FLUIDO, COMO ETANOL, EN EL CUAL EL IOHEXOL ES INSOLUBLE. EN UN PROCEDIMIENTO, EL ETANOL SE AÑADE A UNA SOLUCION ACUOSA DE IOHEXOL. EN OTRO PROCEDIMIENTO, EL IOHEXOL SE SUSPENDE EN ETANOL Y, A CONTINUACION, SE DEJA CRISTALIZAR. DE ESTA FORMA SE PUEDE OBTENER IOHEXOL CRISTALINO CON UN CONTENIDO DE DISOLVENTE RESIDUAL INFERIOR A 100 PPM.
