process for the production of epsilon caprolactam by beckmann - transfer in the gaseous phase in the presence of a zeolithkatalysators and nitrogenous compounds

摘要

epsilon -Caprolactam is prepared by bringing cyclohexanone oxime into contact in gas phase with solid catalysts such as a zeolite catalyst in the presence of at least one nitrogen-containing compound selected from the group consisting of ammonia, methylamines and epsilon -caprolactam.
