1. A method of producing ε
- -caprolactam comprising the Beckmann rearrangement of cyclohexanone oxime in the gaseous phase in a temperature range of 250°
to 450°
C. on MFI zeolite catalysts, wherein said MFI zeolite catalysts have OH groups symmetrically arranged in relation to each other on the surface of said MFI zeolite catalysts due to the lack of central metal atoms.
