Abstract

PROCEDIMIENTO PARA LA FABRICACION DE D(-)AFENIL GLICINA. CONSISTE EN LA DIVISION DE LA DLAFENIL GLICINA CON ACIDO D(B) CANFOR SULFONICO EN PRESENCIA DE UN ACIDO FUERTE EN UNA VASIJA DE REACCION. LA SAL QUE CRISTALIZA SE SEPARA POR FILTRADO Y SE HIDROLIZA POR ADICION DE UNA BASE CON PRECIPITACION DE LA D(-)AFENIL GLICINA. EL ACIDO D(B) CANFOR SULFONICO DISUELTO EN EL AGUA DE RECICLADO Y EL FILTRADO ES SOMETIDO A RACEMIZACION ALCALINA. SE UTILIZA COMO ACIDO EL H2SO4. LA SAL NA DE LA DLAFENIL GLICINA Y LA SAL NA DEL ACIDO CANFOR SULFONICO SON RECICLADOS EN LA VASIJA DE REACCION.
