Abstract
LA PRESENTE INVENCION SE REFIERE AL TRATAMIENTO DE LACTAMAS DIRECTAMENTE OBTENIDAS DE SU PROCEDIMIENTO DE SINTESIS, EVITANDO LO MAS POSIBLE LA FORMACION DE OLIGOMEROS. LA INVENCION CONSISTE MAS CONCRETAMENTE EN UN PROCEDIMIENTO DE TRATAMIENTO DE UNA LACTAMA A PARTIR DEL FLUJO DE REACCION OBTENIDO DE UNA HIDROLISIS CICLIZANTE DE UN AMINONITRILO, CARACTERIZADO PORQUE EL FLUJO DE REACCION QUE SALE DEL REACTOR DE HIDROLISIS SE ENFRIA EN UN INTERVALO DE TIEMPO INFERIOR O IGUAL A 1 HORA A UNA TEMPERATURA INFERIOR O IGUAL A 150 C ANTES DE SU FRACCIONAMIENTO.
