Abstract

SE PRESENTA UN METODO DE PURIFICACION DEL 6-AMINOCAPRONITRILO CALENTANDO UNA MEZCLA QUE CONTENGA EL MISMO Y THA Y CONVIRTIENDO EL THA EN COMPUESTOS DE MAYOR EBULLICION, Y DESTILANDO ENTONCES EL 6AMINOCAPRONITRILO. EL TIEMPO REQUERIDO PARA CONVERTIR EL THA SE REDUCE SI EN LA MEZCLA ESTA PRESENTE UN COMPUESTO DE CARBONIL ORGANICO DURANTE EL CALENTAMIENTO.
