    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: 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.
