Abstract: PROBLEM TO BE SOLVED: To provide a process for hydrogenating an aromatic compound, enabling to perfectly hydrogenate the aromatic compound in a high yield. SOLUTION: This process for hydrogenating an aromatic compound in which a least one hydroxyl group is bonded to an aromatic ring or an aromatic compound in which at least one amino group is bonded to an aromatic ring, in the presence of a catalyst comprising, as catalytically active component, at least one metal of transition group I, VII or VIII of the periodic table applied to a support, wherein the catalyst is obtainable by (a) dissolving the catalytically active compound or a precursor compound thereof in a solvent, (b) admixing the solution thus obtained with an organic polymer which is able to bind at least ten times its own weight of water, giving a swollen polymer, (c) subsequently mixing the swollen polymer with a catalyst support material and (d) shaping, drying and calcining the composition obtained in this way.

Abstract: PROBLEM TO BE SOLVED: To provide a catalyst for the continuous production of 2-butene-1-ol by isomerizing 3-butene-1-ol to remarkably reduce the ratio between a hydrogenation product and a low boiling substance. SOLUTION: A catalyst contains palladium, tellurium or a mixture of selenium and tellurium supported on the support of silicon dioxide and has BET surface area of 80-380m /g and the volume of pores 3nm-300μm in diameter of 0.6-0.95cm /g. The pores 10-100nm in diameter occupy 80-95% of the pore volume. The catalyst is obtained by a method in which the silicon dioxide support is impregnated with the solution of a palladium compound and a selenium compound, a tellurium compound or the mixture of hem and dried, and the compounds are reduced in the presence of hydrogen. The catalyst is used especially for the isomerization of 3-butene-1-ol.

Abstract: Alkines, dienes, and/or singly unsaturated hydrocarbons; compounds containing sulphur, arsenic and/or antimony; oxygen, hydrogen and/or carbon monoxide are removed from material flows in a total of at most three process steps. In a first process step, after hydrogen has been added to the feed material flow at a hydrogenation catalyst which is largely resistant to compounds containing sulphur, arsenic and/or antimony, alkines, dienes and/or singly unsaturated hydrocarbons are removed by hydrogenation, oxygen which may optionally be present also being at least partially removed by hydrogenation. In a second process step, compounds containing sulphur, arsenic and/or antimony and/or residual oxygen from the first process step are removed by absorption on a contact mass, and/or residual oxygen, carbon monoxide and/or residual hydrogen are at least partially converted catalytically into water and carbon dioxide. Optionally, in a third process step, residual carbon monoxide and/or residual hydrogen from the preceding process steps is/are converted on a contact mass into carbon dioxide and/or water.

Abstract: The invention concerns a method of producing compounds containing NH2 groups by the hydrogenation of compounds which include at least one carbon-nitrogen bond with hydrogen in the presence of a catalyst, at a temperature not below room temperature and at an elevated hydrogen partial pressure, optionally in the presence of a solvent. The hydrogenation is carried out under the following conditions: a) a catalyst containing cobalt and/or iron is used, b) if the yield, based on the compound being hydrogenated, and/or the selectivity, based on the desired product, drops below a defined value or if the amount of an undesired side-product increases to more than a defined value, the hydrogenation is interrupted by stopping the feed of the compound being hydrogenated and, if present, also the solvent, c) the catalyst is treated with hydrogen at a temperature in the range 150 to 400 DEG C, using a hydrogen pressure of 0.1 to 30 MPa and a treatment time of 2 to 48 h and d) the hydrogenation is subsequently continued, and the catalysts containing cobalt and/or iron are regenerated.

Abstract: Aliphatic alpha ,w-dinitriles with a phosphorus content of 1.0 ppm or more by weight (ppm wt.) are used for the production of alpha ,w-aminonitriles by partial hydrogenation in presence of a special iron-based catalyst containing a promoter based on aluminium, silicon, zirconium, titanium and/or vanadium. A process for the production of aliphatic alpha ,w-aminonitriles comprises the partial hydrogenation of corresponding dinitriles with a phosphorus content of 1.0 ppm wt. or more in presence of a catalyst containing (a) iron and/or an iron compound, (b) 0.01-5 wt% (based on a) of a promoter based on 2, 3, 4 or 5 elements selected from Al, Si, Zr, Ti and V, and (c) 0-0.5 wt% of an alkali or alkaline earth metal compound. An Independent claim is also included for catalysts with the above composition obtained by the reduction and optional passivation of magnetite, showing a BET surface of 3-10 m /g, a total pore volume of 0.05-0.2 ml/g and an average pore diameter of 0.03-0.1 micron, with 50-70% (by volume) of the pores in the range from 0.01 to 0.1 microns.

Abstract: A process is disclosed for preparing aliphatic alpha , omega -aminonitriles by partially hydrogenating aliphatic alpha , omega -dinitriles at an increased temperature and pressure in the presence of a solvent and a catalyst. The process is characterised in that the catalyst is obtained by thermally decomposing a metal compound selected in the group made up of metal carbonyl compounds, metal salts of C1-C6-carboxylic acids and C2-C6-dicarboxylic acids and metal complexes with diketones until the corresponding metal and/or a metal oxide thereof is obtained, provided that the metal used be nickel or cobalt.

Abstract: The invention relates to a process for producing cyclic lactams by reacting aminocarboxylic acid nitriles with water, in liquid phase, in a fixed bed reactor, in the presence of a catalyst containing a catalytically active oxide comprising no soluble constituent under the reaction conditions. This process is characterised in that the catalyst is composed of shaped bodies which can be obtained by shaping the oxide into shaped bodies and by treating the oxide with an acid which is hardly soluble, having 0.1 to 30 % by weight of the oxide, before or after the shaping process.
