    Abstract: PROBLEM TO BE SOLVED: To remove a halogenized substance from a nitrile mixture for enabling the production of an amine from the nitrile mixture afterwards by heat/treating the nitrile mixture containing the halogenized substance, adding a base to the heat-treated nitrile mixture and removing the base from the neutral mixture. SOLUTION: This method for removing a halogenized material presenting as a form of a phase transition catalyst from a nitrile mixture, is to perform a heat-treatment the nitride mixture containing the halogenized substance at 50-350 deg.C. The heat treatment is performed by setting the pressure and temperature for distilling the nitrile in the mixture at 50 m bar pressure, and 227-230 deg.C bottom temperature and 163 deg.C top temperature. Then, after adding 5-50 wt.% concentration of a base such as NaO into the nitrile mixture while agitating, the halogenized substance is removed from the nitrile mixture. And then, by hydrogenating the obtained nitrile in the presence of a catalyst such as Ni and Co at 60-160 deg.C, especially preferably 90130 deg.C to form an amine.

    Abstract: PROBLEM TO BE SOLVED: To economically and continuously obtain an alkylamine in a simplified apparatus by preheating only an amine stream or only an aldehyde stream fed by separated stream during feed and reacting the amine with the aldehyde on a fixed bed catalyst in a reactor. SOLUTION: Only an aldehyde stream [e.g. formaldehyde aqueous solution having 50-90 wt.%, preferably 65-75 wt.% water content based on total weight of the solution] or only an amine stream (preferably 30-80 wt.% piperazine aqueous solution) fed by separated stream is preheated during a feed (a molar ratio of piperazine to formaldehyde is 1:1.0 to 1:5, preferably 1:2 to 1:2.7) is and the aldehyde is reacted with the amine in a reactor in which these compounds are mixed in a catalyst bed on a fixed bed catalyst in the presence of an isolated hydrogen to continuously provide the objective alkylamine.

    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 reacting an organic compound by which the reaction of the organic compound is performed in extremely high yield or nearly complete conversion by using a specific catalyst. SOLUTION: All organic compound of a monomer and a polymer, especially an organic compound having a treatable group by hydrogen such as C-C double bond and C-C triple bond are reacted in the presence of a uniform ruthenium compound or a mixture of two or more kinds thereof deposited on a carrier in situ in the method for reacting an organic compound. The reaction is preferably hydrogenation, dehydrogenation, hydrogenolysis, amination hydrogenation or dehalogenation. The catalyst is the supported catalyst obtained by subjecting a solution of the ruthenium compound or two or more kinds thereof to pass through in the carrier or on the carrier to form the uniform ruthenium compound or mixture of two or more compound thereof deposited on the carrier. The smallest amount of a byproduct or a degrading product is formed during the hydrogenation and the reaction is performed without separation, after- treatment and recycle of the catalyst in the method.
