    Abstract: A process is described for selectively hydrogenating citronellal to citronellol in which a liquid phase, in which the citronellal is dissolved and particles of a catalyst are suspended which is capable of preferentially hydrogenating carbon-oxygen double bonds over carbon-carbon double bonds, is conducted through a device which inhibits the transport of the catalyst particles in the presence of a hydrogen-containing gas.

    Abstract: Production of saturated carbonyl compounds (I) by selective liquid-phase hydrogenation of alpha , beta -unsaturated carbonyl compounds (II) is carried out in a packed bubble column with the product recycled and by circulating hydrogen gas. Production of saturated carbonyl compounds of formula R1-CH(R2)-CH(R3)-C(R4)=O (I) by selective liquid-phase hydrogenation of alpha , beta -unsaturated carbonyl compounds of formula R1-C(R2)=C(R3)-C(R4)=O (II) in the presence of a particulate palladium and/or rhodium catalyst and a base is carried out in a packed bubble column with the product recycled and by circulating hydrogen gas. R1 = H or an organic group; R2-R4 = H or 1-4C alkyl.
