    Abstract: PROBLEM TO BE SOLVED: To obtain a tertiary amine by allowing nitrile to react with a secondary amine in the presence of a specific palladium catalyst that is improved in its long-term stability and its operation hours. SOLUTION: A nitrile represented by formula I (R and R are each an alkyl, a cycloalkyl, an aryl, an aralkyl; X is an alkyl, a cycloalkyl, amino, hydroxyl; (n) is 1-4; (m) is 1-2), a secondary amine of formula II and hydrogen are allowed to react to one another at 50-250 deg.C under a pressure of 5-350 bar, thus giving the objective amine of formula III. At this time, it is preferable to use a supported palladium catalyst that has 0.1-10 wt.% of Pd, 0.01-10 wt.% of at least one of other metals selected from the group consisting of metals of the group IB, group VIII of the periodic table, cerium, and lanthanum on the support on the basis of the whole catalyst weight.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an amine by a reaction in the presence of a catalyst using a nitrogen compound selected from ammonia, a primary and a secondary amines and hydrogen. SOLUTION: A catalytically active composition of a catalyst after the production and prior to the treatment with hydrogen comprises 22-45 mass % of an oxygen-containing compound of zirconium, 1-30 mass % of an oxygen-containing compound of copper and 5-50 mass % of an oxygen-containing compound of nickel in >1 molar ratio of nickel to copper and further comprises 5-50 mass % of the oxygen-containing compound of cobalt calculated as CoO, 0-5 mass % an oxygen-containing compound of molybdenum and 0-10 mass % of an oxygen-containing compound of the calculated aluminum and/or manganese. Thereby, the economical efficiency of a conventional method is improved and the amine is produced by a technically simple method which can be carried out with a high aldehyde conversion rate and a high ketone conversion rate, a high yield, a high selectivity, a high catalyst useful life and a high mechanical stability of a catalyst molded product.

    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.
