摘要: The present invention relates to a hydrogenation process for the preparation of aromatic amino compounds containing directly on the aryl ring or in a side chain one or more entities that may also undergo hydrogenation, such as carbon multiple bonds, nitrile groups, imino groups or carbonyl groups. The preparation is carried out by catalytic hydrogenation of the corresponding aromatic nitro compounds in the presence of a phosphorus-modified noble metal catalyst. The invention relates also to the use of modified noble metal catalysts for the hydrogenation of aromatic nitro compounds containing carbon multiple bonds and/or substituted by nitrile, imino or carbonyl groups.

摘要: One object of the invention is a process for the catalytic hydrogenation of aromatic nitro compounds in solution or in melt in the presence of hydrogen and at least one noble metal catalyst, nickel catalyst or cobalt catalyst, in which process a catalytic amount of at least one vanadium compound is present, wherein the vanadium has the oxidation state 0, II, IV or V. It has been found that in the catalytic hydrogenation of aromatic nitro compounds the accumulation of hydroxylamines can be almost completely prevented by the addition of catalytic amounts of vanadium compounds, which usually results in concentrations of

摘要: Optically active &agr;-hydroxyethers are prepared from prochiral &agr;-ketoethers by heterogeneous hydrogenation using platinum catalysts in the presence of a chiral nitrogen base in high chemical and optical yields, since this type of hydrogenation selectively hydrogenates only one diastereomer virtually to completion. The yields may be substantially increased by adding a solid, strong base which has a racemizing effect on the non-hydrogenatable diasteromer.
