Abstract An apparatus for the production of epsilon -caprolactam is provided which comprises (1) a fluidized bed reactor having a solid catalyst therein for subjecting cyclohexanone oxime to a rearrangement reaction to obtain a reaction product containing unreacted cyclohexanone oxime and (2) a fixed bed reactor packed with a solid catalyst for subjecting the unreacted cyclohexanone oxime to a rearrangement reaction to obtain epsilon -caprolactam. Using the apparatus, epsilon -Caprolactam is obtained with a high yield.
