Abstract
PROCEDIMIENTO PARA LA OBTENCION DE AMIDA DE ACIDO NICOTINICO PURA A PARTIR DE AMIDA DE ACIDO NICOTINICO BRUTA. LA AMIDA DE ACIDO NICOTINICO BRUTA SE RECRISTALIZA EN UN ALCANOL, USANDOSE COMO DISOLVENTE 2-MWETILPROPANOL (1) CON HASTA 10-18 POR 100 EN PESO DE AGUA, DISOLVIENDOSE LA AMIDA EN EL A UNA TEMPERATURA COMPRENDIDA ENTRE 65 Y 85 C. POSTERIORMENTE LA SOLUCION CALIENTE SE TRATA CON INTERCAMBIADORES DE IONES, DEPENDIENDO CUALES SEAN ESTOS DEL TIPO DE IMPUREZAS DE LA AMIDA. TRAS ESTO LA SOLUCION SE ENFRIA Y LA AMIDA DE ACIDO NICOTINICO PURA SE SEPARA, PUDIENDOSE EMPLEAR LAS AGUAS MADRES PARA UNA CARGA ULTERIOR.
