Abstract

PROCEDIMIENTO PARA SEPARAR LOS AMINOACIDOS LEUCINA, ISOLEUCINA Y VALINA SIN EMPLEO DE PRECIPITANTES TOXICOS U OFENSIVOS. CONSISTENTE EN UN ENRIQUECIMIENTO POR ETAPAS DE ISOLEUCINA Y VALINA EN LAS AGUAS MADRES, PARA UNA CRISTALIZACION DE LEUCINA EN EL CAMPO DE PH DE 1,5 A 2,0 Y UNA INVERSION DE ESTAS CIRCUNSTANCIAS POR CRISTALIZACION DE CLORHIDRATO DE ISOLEUCINA A PARTIR DE ACIDO CLORHIDRICO CONCENTRADO, Y ENRIQUECIMIENTO DE LA LEUCINA EN LAS AGUAS MADRES. EN VIRTUD DE ESTA INVERSION DEL COMPORTAMIENTO DE SOLUBILIDAD DE LOS CITADOS AMINOACIDOS EN LOS DOS DISTINTOS SISTEMAS, SE LOGRA SU SEPARACION MEDIANTE UNA SIMPLE CRISTALIZACION FRACCIONADA.
