Abstract: Carbonyl compounds R1-CHR2-CHR3-CR4O (I, R1=H or an organic radical; R2-R4=H or C1-C4-alkyl) are prepared by selective hydrogenation of the alpha , beta -unsaturated carbonyl compounds R1-CR2=CR3-CR4O (II) in the liquid phase by means of hydrogen in the presence of a palladium catalyst and of from 15 to 50% by weight, based on (II), of a tertiary amine.

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 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: 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.
