    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a secondary amine in a high yield and selectivity by selecting nitrile using hydrogen in the presence of a catalyst. SOLUTION: In this method for producing a secondary amine represented by general formula (II) (X-CH2-)2NH (II) [X is an alkyl, an alkenyl or a cycloalkyl group] (II), a nitrile represented by general formula (III) X-CN (III) is reacted with hydrogen at 20-250 deg.C under 60-350 bar in the presence of 0.1-5 mass % based on the total amount of Rh and a catalyst on a carrier of a RH-containing catalyst to form a mixture of a primary amine represented by general formula (I) X-CH2-NH2 (I) and the secondary amine represented by general formula (II) (X-CH2-)2NH (II) and at least a part of the primary amine separated from the obtained mixture is returned to the reaction.

    Abstract: PROBLEM TO BE SOLVED: To provide a process for the continuous hydrogenation of a nitrile to a primary amine, by which the mild hydrogenation of the nitrile can simply be carried out and especially by which the formation of the primary amine in high selectivity and the avoidance of a secondary treatment such as the separation of the nitrile can be achieved. SOLUTION: In this process for the continuous hydrogenation of the nitrile to the primary amine in a liquid phase over a suspended, activated Raney catalyst based on an alloy of aluminum and at least one transition metal selected from the group consisting of iron, cobalt and nickel, and, if desired, one or more further transition metals selected from the group consisting of titanium, zirconium, chromium and manganese, the hydrogenation is carried out in the absence of ammonia and basic alkali metal compounds or alkaline earth metal compounds.

    Abstract: PROBLEM TO BE SOLVED: To provide a technically simple method effectively, selectively and economically producing N-methyl-2-pyrrolidone(NMP) in high space-time yield (based on γ-butyrolactone) (γ-BL) from ammonia, methanol and γ-BL. SOLUTION: This method produces NMP in two steps, reacting ammonia with methanol in the presence of a catalyst at a high temperature to produce a mixture including monomethylamine, dimethylamine, trimethylamine and ammonia, separating ammonia in a first step and then reacting the mixture including methylamine with γ-BL in a molar ratio of monomethylamine/γ-BL >=1 at a high temperature and an overpressure, separating NMP and unreacted methylamine from the reaction product and returning the unreacted methylamine to the first step to react with methanol and ammonia.

    Abstract: The invention relates to a method for producing amines of general formula (I) X(-CH2-NHR)n in which R independently represents C1-200-alkyl, C3-8-cycloalkyl, C4-20-alkyl cycloalkyl, C4-20-cylcoalkyl alkyl, C2-20-alkoxyalkyl, aryl, C7-20-alkylaryl, C7-20-aryl alkyl, C2-8-hyrodoxyalkyl, C2-8-mercaptoalkyl, C8-20-aryloxyalkyl or jointly represents a saturated or unsaturated C2-6-alkylene chain which is optionally substituted singly to triply by C1-4-alkyl and is optionally interrupted by oxygen or nitrogen. X is a C1-20-alkyl, C2-20-alkenyl or C3-8-cycloalkyl with n free valances optionally substituted by C1-20-alkyl, C3-8-cycloalkyl, C4-20-alkyl cycloalkyl, C4-20-cycloalkyl alkyl, C2-20-alkoxyalkyl, aryl, C7-20-alkylaryl, C7-20-aryl alkyl, C1-20-alkoxy, hydroxy, C1-20-hyrodoxyalkyl, amino, C1-20-alkyl amino, C2-20-dialkyl amino, C2-12-alkenyl amino, C3-8-cycloalkyl amino, aryl amino, diaryl amino, aryl-C1-8-alkyl amino, halogen, mercapto, C2-20-alkenyloxy, C3-8-cycloalkoxy, aryloxy, and C2-8-alkoxycarbonyl, and n is a whole number from 1 to 4. The amines are produced by reacting nitriles of general formula (II) X(-CN)n in which X and n have the above mentioned meanings with primary amines of general formula (III) H2NR in which R has the above mentioned meanings, and with hydrogen at temperatures ranging from 50 to 250 DEG C and pressure ranging from 5 to 350 bar in the presence of a catalyst containing Pd, whereby the catalyst comprises 0.1 to 10 wt. % Pd on a carrier, said wt. % being relative to the total weight of the catalyst.
