Abstract

Se refiere al tratamiento de lactamas que provienen directamente de su procedimiento de síntesis, evitando lo más que sea posible la formacion deoligomeros. Consiste más precisamente en un procedimiento de tratamiento de una lactama partiendo del flujo de reaccion resultante de una hidrolisis ciclizantede un aminonitrilo donde el flujo de reaccion que sale del reactor de hidrolisis se enfría en un lapso inferior o igual a 1 hora a una temperaturainferior o igual a 150°C antes de su fraccionamiento.
