Abstract

LA INVENCION PROPORCIONA UN PROCEDIMIENTO DE RECUPERACION DE ACIDO LACTICO A PARTIR DE SOLUCIONES ACUOSAS, QUE CONTIENE AL MENOS UNA SAL DE LACTATO HIDROSOLUBLE, Y TIENE UN PH COMPRENDIDO ENTRE APROX. 4 Y 14. DICHO PROCEDIMIENTO COMPRENDE LAS SIGUIENTES FASES: PONER EN CONTACTO DICHA SOLUCION ACUOSA CON UN INTERCAMBIADOR DE CATIONES QUE SE ENCUENTRA, AL MENOS PARCIALMENTE, EN SU FORMA ACIDA, DICHO INTERCAMBIADOR DE CATIONES ES INMISCIBLE EN AGUA, TANTO EN SU FORMA ACIDA COMO EN SU FORMA DE SAL; EFECTUAR EL INTERCAMBIO DE IONES, EN EL QUE LOS PROTONES SE TRANSFIEREN DESDE EL INTERCAMBIADOR DE CATIONES HASTA LA SOLUCION ACUOSA, PARA ACIDULARLA Y FORMAR ACIDO LACTICO EN LA MISMA, Y LOS CATIONES DE LA SOLUCION ACUOSA SE UNEN AL INTERCAMBIADOR DE CATIONES; HACER REACCIONAR EL INTERCAMBIADOR CATIONICO QUE PORTA LOS CATIONES, PARA CONVERTIRLO EN UN INTERCAMBIADOR CATIONICO QUE SE PRESENTA, AL MENOS PARCIALMENTE, EN FORMA ACIDA Y EN UN SEGUNDO PRODUCTO, EL CUAL ES BASICO Y COMPRENDE EL CATION DE LASAL; Y RECUPERAR EL ACIDO LACTICO A PARTIR DE LA SOLUCION ACUOSA ACIDULADA QUE CONTIENE ACIDO LACTICO, MEDIANTE LOS PROCEDIMIENTOS CONOCIDOS PER SE.
