Abstract: A process for the preparation of caprolactam wherein, in a first stage, cyclohexanone-oxime is vaporized, in the presence of inert gases, by bringing it into contact with a fluidized bed of inert solid particles at from 150 DEG to 250 DEG C., and the mixture of cyclohexanone-oxime vapor and inert gases is passed into a second stage, where the cyclohexanone-oxime is rearranged to caprolactam at from 230 DEG to 450 DEG C. over a supported catalyst, containing boron trioxide, in a fluidized bed.
