Abstract
La presente invención se refiere a procedimiento para retirar n-parafinas con un número de átomos de carbono comprendido entre 12 y 18 de la mezcla de dichas n-parafinas con ácidos parafinosulfónicos con el mismo número de átomos de carbono, agua y ácido sulfúrico donde dichas mezclas se obtienen por sulfurización con SO2 y O2 en presencia de agua y de radiaciones ultravioletas de mezclas de n-parafinas C12-C18 a una temperatura de 25-50 grados C, comprendiendo la eliminación del exceso de SO2, en caso de presentarse, de la mezcla de reacción proviniente del reactor de síntesis de los ácidos parafinosulfónicos y decantar la mezcla para retirar la mayor parte de las parafinas de una mezcla residual caracterizado porque la mezcla residual se deshidrata (se le quita la mayor parte del agua) hasta la formación de un sistema bifásico, por lo menos hasta obtener un enturbiamiento de la mezcla y la mezcla deshidratada se extracta con CO2 supercrítico que retira todas o substancialmente todas la parafinas reisduales.
