Abstract

Procedimiento para la producción de epsilon-caprolactama, caracterizado porque comprende transponer ciclohexanonoximas en fase gaseosa, en presencia de un catalizador conteniendo boro, en lecho fluidificado, a una temperatura de 250 a 400ºC, bajo introducción, en forma líquida, de residuos de la destilación de ciclohexanonoxima en una cantidad de 5 hasta 500 veces la cantidad de ciclohexanonoxima en forma vaporizada y, como mínimo, 50 veces la cantidad de gas inerte, tal como nitrógeno.
