Abstract

LA INVENCION SE REFIERE A LA RECUPERACION DE UN SOLVENTE POLAR APROTICO A PARTIR DE UNA SOLUCION ACUOSA SALINA DE ESTE SOLVENTE, POR UN PROCESO QUE CONSISTE EN DESALAR DICHA SOLUCION POR ELECTRODIALISIS Y DESPUES EN DESTILAR LA SOLUCION DESALADA. PARA EVITAR LA PRECIPITACION DE HIDROXIDOS METALICOS DURANTE LA ELECTRODIALISIS, SE MANTIENE LA SALMUERA A UN PH ACIDO.
