Combined production of cyclic lactam and cyclic amine, e.g. caprolactam and azepane, involves gas phase reaction of aliphatic alpha,omega-diamine with water over heterogeneous catalyst

摘要

Combined production of a cyclic lactam (I) and a cyclic amine (II) comprises reacting an aliphatic alpha ,w-diamine (III) with water in the gas phase in the presence of a heterogeneous catalyst.
