Abstract: PROBLEM TO BE SOLVED: To produce a carried catalyst used for converting a carboxylic acid or its ester into an aldehyde by a selective hydrogenation reaction, having reasonable stability, capable of being regenerated, hardly or quite not forming a by-product, having at least comparable selectivity with the corresponding non-carried catalyst. SOLUTION: This method for producing an aldehyde of formula I (R is an aliphatic, alicyclic, aromatic or aromatic aliphatic group which may be substituted, if necessary, with one or more substituents and/or if necessary, may have more heterogeneous atom) comprises selectively hydrogenating an acid of the formula: R-COOH or an ester of the acid with a 1-10C alcohol with hydrogen in the presence of a metal oxide catalyst in a gaseous phase. Therein, the hydrogenation is carried out in the presence of the carried catalyst containing a metal oxide suitable for the selective hydrogenation of the carboxylic acid or the carboxylate ester as an essential catalyst on SiC (silicon carbide) as a carrier at a temperature of 150-450 deg.C under a pressure of 0.1-150 bars.

Abstract: PROBLEM TO BE SOLVED: To provide a method for industrially efficiently and continuously producing an aldehyde by hydrogenating an ester, while recycling the unused hydrogen and the unreacted ester, wherein the selectivity of the aldehyde is maintained at a satisfactory level. SOLUTION: This method for producing an aldehyde of the formula: R-CHO comprises hydrogenating an ester of the formula: R-COOR' (R is a non- substituted or substituted aliphatic group, alicyclic group, aromatic group or aralkyl group; R' is a group derived from a 1-10C alcohol] with excessive hydrogen in an amount of 2-200 moles per mole of the ester in the presence of a heterogeneous hydrogenation catalyst at 200-450 deg.C in a gas phase, while recycling the unreacted hydrogen and the unreacted ester. Therein, the alcohol is removed from the recycling flow in such an extent as the initial concentration of the produced alcohol: R'-OH in the reaction mixture is maximally 1 mole per mole of the carboxylic acid ester II.

Abstract: PROBLEM TO BE SOLVED: To obtain zirconium dioxide having high monoclinic system ratio end large BET surface area. SOLUTION: This zirconium dioxide is composed of at least 80 wt.% of monoclinic system and has a BET surface area of at least 100 m /g. The production method consists of a process for forming precipitates by mixing a zirconium salt aqueous solution with ammonia, and the drying and calcination of the resultant precipitates. In this process, the precipitates formed in the aqueous solution is aged at 0-300 deg.C and calcined at 200-600 deg.C, before drying. This product can be used as a formed product, a catalyst or a catalyst support.

Abstract: PROBLEM TO BE SOLVED: To provide an amination catalyst small in the content of nickel and/or cobalt and having high selectivity and high stability about ethylene diamine obtained by aminating monoethanol amine with ammonia. SOLUTION: The catalyst is obtained by carrying 6-50wt.% cobalt, nickel or the mixture, 0.001-25wt.% ruthenium, 0-10wt.% copper and 0-5wt.% accelerator per total weight of the catalyst on a porous metal oxide carrier. In such a case, the catalyst is produced by (a) impregnating the carrier with the metal and the accelerator or the compound, (b) drying and calcining and (c) reducing with hydrogen flow, where without impregnating the carrier with a halogen compound.

Abstract: Preparation of amines from alcohols, nitrogen compounds and hydrogen is effected over a catalyst containing oxygenated compounds of zirconium, copper, nickel and optionally aluminium and/or manganese. Preparation of amines involves reacting primary or secondary alcohols, nitrogen compounds selected from ammonia and primary or secondary amines, with hydrogen at 80-250 degrees C and 0.1-40 MPa over a catalyst at least containing zirconium, copper and nickel. Specifically, the catalytically active mass contains metal oxides of Zr (20-85 wt. %, as ZrO2), Cu (1-30 wt.%, as CuO), Ni (14-70 wt.%, as NiO) and optionally aluminium and/or magnesium (0-10 wt.%, as Al2O3 and/or MnO2). The molar ratio of Ni / Cu is ≥ 1, and the catalyst is free of cobalt or molybdenum oxides. An Independent claim is also included for a catalyst formed.
