Abstract: In a process for hydrogenating unsubstituted monocyclic or polycyclic aromatics or monocyclic or polycyclic aromatics substituted by at least one alkyl group, amino group or hydroxyl group or a combination of two or more thereof to form the corresponding cycloaliphatics by means of gaseous hydrogen in the presence of at least one catalyst in a reaction column (4) in which the reactants are passed over the catalyst(s) (5) fixed in the reaction column (4), the cycloaliphatics are taken off at a side offtake (14) or from the bottom of the column (6) through a line (8) or at the side offtake (14) and from the bottom of the column (6) through a line (8).

Abstract: The present invention relates to a continuous process for the preparation of cinnamaldehyde or cinnamaldehyde derivatives by continuous reaction of benzaldehyde derivatives with alkanals in the presence of bases and optionally subsequent continuous hydrogenation in a circulation reactor in the presence of a suspension catalyst and hydrogen to give dihydrocinnamaldehyde derivatives.

Abstract: Ordered packing (1) for a reactor has flow deviating sheets (A, B) arranged in the longitudinal direction of the reactor and parallel with a heating/cooling casing. Corrugated flow deviating sheets (A) are alternately arranged with planar flow deviating sheets (B) forming flow deviating channels (2). The flow deviating sheets (A) completely fill the cross-section of the reactor and the flow deviating sheets (B) expose an edge gap (3) on the inner wall of the reactor. Preferred Features: The edge gap is formed in a non uniform manner over the cross-section of the reactor having the largest possible radial extension in regions of the inner wall of the reactor into which flow deviating channels protrude and having the smallest possible radial extension in which flow deviating channels do not protrude. The flow deviating channels contain inert material and/or catalyst material.

Abstract: Selective liquid hydrogenation of carbonyl compounds to the corresponding alcohols is effected using a platinum/zinc oxide catalyst. Selective liquid hydrogenation of carbonyl compounds of formula R C(O)R (I) to the corresponding alcohols of formula R C(OH)R (II) is effected using a platinum/zinc oxide catalyst. R and R = H, optionally mono- or poly-unsaturated, optionally substituted 1-20C alkyl, optionally substituted aryl or optionally substituted heterocyclic group.

Abstract: Selective catalytic gas-phase hydrogenation of alkynes, dienes, alkenynes and/or polyenes in an olefin-containing hydrocarbon stream in a series of two or more reaction zones without feeding part of the hydrocarbon stream between the penultimate and last reaction zones. The process comprises adjusting the hydrogen content before the penultimate zone and the conversion in the penultimate zone so that the reaction mixture leaving the penultimate zone contains at least 0.7 vol.% hydrogen.
