    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 for producing anhydrous 2-amino-1- methoxypropane, capable of obtaining a desired product in high yield. SOLUTION: (a) Two phases comprising a reaction mixture and sodium hydroxide solution, obtained by reaction of 1-methoxy-2-propanol with ammonia on a catalyst are formed and (b) 2-amino-1-methoxypropane-containing phase is separated from water phase and (c) 2-amino-1-methoxypropane-containing phase is subjected to azeotropic distillation to produce an azeotropic mixture at first and the azeotropic mixture is returned to a process (a) or (b), and then, anhydrous 2-amino-1-methoxypropane is produced.

    Abstract: Production of anhydrous 2-amino-1-methoxypropane (I) comprises (a) treating an aqueous reaction mixture (II) containing (I), obtained by reacting 1-methoxy-2-propanol with ammonia (NH3) on a catalyst, with aqueous sodium hydroxide (NaOH) solution to form an aqueous phase containing aqueous NaOH solution and a phase containing (I); (b) separating the phase (III) containing (I) from the aqueous phase; and (c) distilling (III) to separate an azeotrope of water and (I), which is recycled to step (a) or (b), and then anhydrous (I). Also claimed is a method of separating water from (II) in this way.
