Abstract: Olefinically unsaturated alcohols (I) are prepared by selective hydrogenation of the corresponding carbonyl compounds (II) in the liquid phase with hydrogen, using an Ru, Rh, Os, Ir or Pt catalyst and carrying out the hydrogenation in the presence of from 5 to 40% by weight, based on (II), of a tertiary amine. The process is of particular importance for the selective hydrogenation of alpha , beta -unsaturated carbonyl compounds (IIa) and amongst these specifically for the hydrogenation of citral to geraniol and nerol. The preferred amine is trimethylamine.

Abstract: Prodn. of a Pd-C catalyst involves redn. of Pd cpds. by adding a soln. of a Pd salt to an organic solvent (MeOH) contg. O gps. in the presence of suspended C, with stirring in a H2 atmos. Pref. redn. is carried out in normal or elevated pressure, pref. 1-10 bar. The C carrier can be powdered active charcoal, C black or graphite. Catalyst is used in the hydrogenation and hydrogenative cracking of organic cpds. Method gives a partic. active catalyst.

Abstract: Ruthenium-on-charcoal and ruthenium-on-carbon black catalysts, containing from 0.1 to 5% by weight of iron, for the preparation of olefinically unsaturated alcohols by selective hydrogenation of the corresponding +60, beta -unsaturated carbonyl compounds in the liquid phase are prepared by modifying the catalyst with iron only after it has been impregnated with the ruthenium compound, and reducing the catalyst with hydrogen at from 400 DEG to 600 DEG C., with thorough mixing. The catalysts according to the invention are particularly useful for improving the industrially difficult hydrogenation of citral to give the soughtafter fragrances geraniol and nerol.

Abstract: Olefinically unsaturated carbonyl compounds R1-CHR2-CHR3-C(R4)O (I) and alcohols R1-CHR2-CHR3-CH(R4)-OH (II) (where R1 is an olefinically unsaturated organic radical, and R2, R3 and R4 are H or C1-C4-alkyl) are prepared by hydrogenating the carbonyl compounds R1-CR2=CR3-C(R4)O (III) in the liquid phase with hydrogen, using a catalyst system comprising, firstly, Pd and, secondly, Ru, Rh, Os, Ir or Pt, in the presence of from 5 to 40% by weight, based on (III), of a tertiary amine, under a hydrogen pressure of from 1 to 20 bar is predominantly (I) is to be obtained and from 20 to 150 bar if predominantly (II) is to be obtained. The process is of particular importance for the hydrogenation of citral (IIIa) to give citronellal (Ia) or citronellol (IIa), the preferred amine being trimethylamine.

Abstract: Catalyst for hydrogenation of organic cpds. contains one or more complexes of Pd(O) on an inert carrier. This catalyst is very active, esp. with respect to hydrogenation of organic nitro or carbonyl cpds., nitriles, olefins and cycloolefins. The reaction is highly selective, esp. in the case of aromatic and polycyclic nitro cpds. The Pd(O) complexes are stable and firmly adhere to the carrier. The organic ligands protect Pd atoms against oxidation. The dispersion of Pd atoms is very fine. The pref. ligands include unsatd. ketones of formula (in which R1 and R6 are each H, 1-5C alkyl, phenyl or 5-8C cycloalkyl; and R2, R3, R4 and R5 are each H (pref.) or 1-5C alkyls).
