Abstract
PROCEDIMIENTO PARA EL AISLAMIENTO Y PURIFICACION DE ACIDOS LIBRES A PARTIR DE SUS SALES POR ELECTRODIALISIS MEDIANTE UNA CELDA DE ELECTRODIALISIS DE 4 COMPARTIMENTOS, ESTANDO LOS DOS COMPARTIMENTOS ADYACENTES (A, D) A LOS ELECTRODOS, SEPARADOS DE LOS COMPARTIMENTOS CENTRALES (B, C) MEDIANTE MEMBRANAS CATIONICAS (2, 3), MIENTRAS QUE LOS COMPARTIMENTOS CENTRALES ESTAN SEPARADOS ENTRE SI POR UNA MEMBRANA ANIONICA (1), RECIRCULANDOSE POR (A) UN ANOLITO, POR (B) AGUA O UNA DISOLUCION DILUIDA DEL ACIDO A AISLAR, POR (C) UNA DISOLUCION ACUOSA DE LA SAL DEL ACIDO A AISLAR Y POR (D) UN CATOLITO, CARACTERIZADO PORQUE AL APLICAR UNA DIFERENCIA DE POTENCIAL ENTRE LOS ELECTRODOS, SE PRODUCE LA MIGRACION DE LOS IONES DE FORMA QUE SE OBTIENE UN ACIDO LIBRE PURO EN EL COMPARTIMENTO (B). EL PROCEDIMIENTO PERMITE OBTENER ACIDO LIBRE SIN COEXISTIR CON SU SAL EN UN MISMO COMPARTIMENTO, LO QUE AUMENTA SU PUREZA. EL PROCEDIMIENTO ES ADECUADO PARA PURIFICAR MULTITUD DE ACIDOS, ESPECIALMENTE EL ACIDO IMINODIACETICO (IDA).
