    Abstract: A process is provided for producing ε-caprolactam from cyclohexanone oxime. The process comprises a evaporation step of a mixture of cyclohexanone oxime and a solvent by introducing the mixture into a fluidized bed in which inert particles is fluidized by an inert gas, the particles having heat enough to evaporate the mixture; and a rearrangement step of cyclohexanone oxime in the evaporated mixture into ε-caprolactam by a gas phase Beckmann rearrangement reaction using a solid catalyst, excluding a catalyst consisting of a boric acid or a boron oxide.
