Abstract: PROBLEM TO BE SOLVED: To carry out the hydrogenation of especially citral to citronellal at a low cost by an economical process having improved space-time yield and reduced investment cost by hydrogenating an α,β-unsaturated carbonyl compound in liquid phase under specific condition. SOLUTION: A compound of formula II is produced by the hydrogenation of an α,β-unsaturated carbonyl compound of formula I (R1 is H or an organic group; R2 to R4 are each H or a 1-4C alkyl) with hydrogen in the presence of powdery palladium and/or rhodium and an organic group while performing the regeneration of the product and the circulation of hydrogen gas in a bubble packed column reactor. The packing material in the bubble column reactor preferably has a hydraulic diameter of 0.5-20 mm and a surface roughness of 0.1 to 10 times the average particle diameter of the powdery catalyst particles at the opening or the channel wall part of the packing material and is made of a metallic material, a plastic material, etc.

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.
