Abstract

UNA GRAN CANTIDAD DE PROCESOS HABITUALES PARA LA SEPARACION DE AMINOACIDOS FALLAN, SI AMINOACIDOS HIDROFILOS MUY POLARIZADOS DEBEN SER SEPARADOS CON PUNTOS ISOELECTRICOS (IEP) QUE SE ENCUENTRAN MUY PROXIMOS. MEZCLAS DE L-ACIDO GLUTAMICO (IEP = 3,24) Y L-FOSFONOTRICIN (IEP = 2,6) QUE SE PRESENTAN EN LA TRANSAMINIZACION ENCIMATICA DEL CORRESPONDIENTE (ALFA)-ACIDO CETONICO, HAN SIDO HASTA AHORA MUY DIFICILES DE SEPARAR. EL OBJETO DE LA PRESENTE INVENCION ES UN PROCESO PARA LA SEPARACION DEL L-FOSFINOTRICIN Y L-ACIDO GLUTAMICO DE TALES CARACTERISTICA QUE LA SEPARACION SE REALIZA COMO EXTRACCION LIQUIDO-LIQUIDO CON DOS FASES ACUOSAS NO MEZCLABLES COMO SISTEMA DE FASES, EN EL QUE ESTA CONTENIDA UNA COMBINACION COMO CONFORMADOR DE FASE EN EL SISTEMA DE FASES DE AL MENOS DOS POLIMEROS SOLUBLES EN AGUA DIFERENTES O AL MENOS UNA SAL SOLUBLE EN AGUA Y UN POLIMERO SOLUBLE TAMBIEN EN AGUA Y LA EXTRACCION EN VARIAS ETAPAS EN CONTRACORRIENTE SE REALIZA SEGUN EL PRINCIPIO DE LA DISTRIBUCION DIJCK.
