    Abstract: PROBLEM TO BE SOLVED: To simultaneously solve the unfavorable problems of a catalyst to be used for a fluidized-bed method, including low flowability, low abrasiveness, and low transmission property.
    SOLUTION: The carrier catalyst for ammooxidation comprises (a) a carrier material containing aluminum oxide, silicon dioxide, titanium dioxide, and/or zirconium dioxide and (b) an active material containing as essential compositions vanadium and antimony in oxidic form, wherein the content of the carrier material is 80 wt.% or more of the total weight of the carrier catalyst. The carrier catalyst for ammonoxidation is obtained by (1) impregnating the carrier material with a solution or a suspension of a compound containing the active material, (2) separating and removing an excess amount of liquid from the thus obtained mixture, (3) drying the impregnated carrier material, and (4) calcining the impregnated carrier material under oxidation conditions.

    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 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.

SOLUTION: When (A) an alcohol (preferably an α,ω-diol) is reacted with (B) an alkylamine or a dialkylamine (preferably monomethylamine, etc.), the reaction is carried out in the presence of (C) a catalyst prepared by including 0-2 wt.% BaO, Cr2 O3 and/or ZnO in copper and magnesium silicate as a base regardless thereof for each time as the catalyst. The component C preferably contains 30-60 wt.% CuO and has preferably at least 100 m /g BET specific surface area.
