Abstract
UN PROCESO METATETICO ACIDO-SAL MEDIADO POR UNA MEMBRANA INTERCAMBIADORA DE CATIONES. SE DISPONE UNA SOLUCION SALINA ACUOSA EN UN PRIMER COMPARTIMIENTO EN UN LADO DE LA MEMBRANA JUNTO CON UN EXTRACTANTE ORGANICO AMINICO DE LIMITADA MISCIBILIDAD EN AGUA, Y SE DISPONE UNA SOLUCION ACIDA ACUOSA EN UN SEGUNDO COMPARTIMIENTO EN EL OTRO LADO DE LA MEMBRANA. SE FORMA PRODUCTO ACIDO EN EL PRIMER COMPARTIMIENTO QUE SE RECOGE EN EL EXTRACTANTE ORGANICO AMINICO DE DONDE SE RECUPERA. EL PROCESO ES PARTICULARMENTE ADECUADO PARA LA RECUPERACION DE UN ACIDO CARBOXILICO A PARTIR DE SU SAL.
