摘要

Disclosed is a process for selectively producing aliphatic cyclic amines which comprises reacting a dihydric alcohol characterized by four to six carbons, preferably 1,5-pentane diol, with excess ammonia in presence of ZSM-5 catalyst modified with group of elements nickel, copper or cobalt-containing, at a temperature of at least 250° C., wherein said catalyst incorporates at least one metal.
