Abstract
Procedimiento para la producción de epsilon-caprolactama, caracterizado porque comprende transponer ciclohexanonoxima en fase gaseosa, en presencia de un catalizador conteniendo ácido bórico, en lecho fluidificado, en presencia de un gas inerte, de modo que mediante la introducción de tubos verticales en el reactor, el diámetro de las zonas no estacionarias libres de catalizador, que se presentan en el lecho fluidificado, esté comprendido entre 5 y 40 cm, preferentemente entre 8 y 20 cm.
