    Abstract: PROBLEM TO BE SOLVED: To enable to industrially simply and profitably obtain the subject compound from a primary amine and a diol by using a specific copper- containing hydrogenation/dehydrogenation catalyst. SOLUTION: This method for producing an N-substituted cyclic amine of formula I comprises reacting (C) a compound of the formula: R -NH2 [R is an (alkoxy)alkyl, an aryl, etc.,] with (D) a compound of the formula: HO-A-OH A is an alkylene (substituted by a group of the formula: R (R is R ), a group of the formula: (CH2 )n -[O-(CH )m ]r , [(m), (n) are each 2-8; (r) is 1-3]} in the presence of a coppercontaining catalyst. The copper-containing catalyst is obtained by impregnating an inactive carrier (e.g. silicon dioxide, a silicate or zeolite) with (A) hydrogen and (B) the aqueous ammine complex solution of an easily pyrolytic copper compound (e.g. copper carbonate, copper oxalate or copper formate)(preferably an ammoniacal copper carbonate solution), drying the impregnated carrier, and subsequently calcining the dried product, and contains the copper in an amount of 5-50wt.% converted into CuO on the basis of the whole amount of the calcined catalyst.

    Abstract: PROBLEM TO BE SOLVED: To provide a method which effects the subject reaction in the vapor phase advantageously from industrial, economical and environmental aspects in the presence of a catalyst composed of copper and Na2 O supported by a carrier composed of SiO2 and CaO. SOLUTION: This method effects the subject reaction in the presence of free hydrogen by passing 1,4-butanediol over an immobilized phase of catalyst composed of 4 to 40wt.%, preferably 4 to 32wt.%, of copper and 0 to 5wt.%, preferably 0 to 2wt.%, of Na2 O, each percentage being based on the total quantity of the catalyst, supported by a carrier composed of 80 to 100wt.%, preferably 90 to 100wt.%, of SiO2 and 0 to 20wt.%, preferably 0 to 10wt.%, of CaO, where the copper grains having an average diameter of 10 to 100nm are dispersed at a rate of 20 to 50% so as to have a surface area of 10 to 50m /g over the carrier, under the conditions of temperature: 150 to 300 deg.C, preferably 190 to 230 deg.C, absolute pressure: 1 to 40 bar, preferably about 1 bar, and hourly space velocity of 1,4-butanediol: 0.2 to 20kg, preferably 0.5 to 7.5kg, per kg copper, with the carrier gas containing free hydrogen being reused as the recycle gas.
