Abstract

LA PRESENTE INVENCION SE DIRIGE A LA NECESIDAD DE SUMINISTRAR UN PROCESO PARA PURIFICAR VALINA QUE TENGA UNA ALTA PUREZA DE ALTA PRODUCCION POR UN METODO SENCILLO Y USANDO UN PRECIPITANTE BARATO. UNA DISOLUCION ACUOSA QUE CONTIENE VALINA ES REACCIONADA CON ACIDO P-ISOPROPILBENCENOSULFONICO O SU SAL SOLUBLE EN AGUA PARA FORMAR UN CRISTAL DE P-ISOPROPILBENCENOSULFONATO DE VALINA. EL P-ISOPROPILBENCENOSULFONATO DE VALINA ES SEPARADO Y DESPUES DISOCIADO PARA PURIFICAR Y OBTENER VALINA. EL ACIDO PISOPROPILBENCENOSULFONICO USADO PUEDE ESTAR EN FORMA DE ACIDO LIBRE, O UNA SAL COMO POR EJEMPLO UNA SAL DE METALICA ALCALINA O UNA SAL AMONICA. EL PROCEDIMIENTO PARA LA FORMACION DE UN ADUCTO COMPRENDE 1 MOL DE VALINA Y 1 MOL DE ACIDO P-ISOPROPILBENCENOSULFONICO Y LA PURIFICACION DE VALINA PRODUCE LOS EFECTOS DE QUE COMO LA SOLUBILIDAD DEL P-ISOPROPILBENCENOSULFONATO DE VALINA ES BAJA, LA VALINA PUEDE SER OBTENIDA EN ALTA EFICACIA, Y DE QUE LA VALINA PUEDE SER SEPARADA EN ALTA VELOCIDAD DE LA LEUCINA YDE LA ISOLEUCINA LAS CUALES SON EN GENERAL DIFICILES DE SEPARAR DE LA VALINA, A CAUSA DE LA ESPECIFIDAD DEL ADUCTO. EL ACIDO PISOPROPILBENCENOSULFONICO PUEDE SER FACILMENTE PRODUCIDO SULFONANDO ISOPROPILBENCENO BARATO.
