Applications

Rhodium, 5% on carbon is a useful reagent for the conversation of nitriles to primary amines and the hydrogenation of aromatic rings, pyridines, aldehydes and sugars. It is also used for the reduction of oximes to amines and for the reduction of nitrobenzene to phenylhydroxylamine using hydrazine hydrate as the hydrogen source.

Notes

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents, halogens, chlorine trifluoride and oxygen difluoride.

Rhodium catalysts are especially useful for the hydrogenation of aromatic rings under mild conditions. For details for the hydrogenation of 4-aminobenzoic acid to its hexahydro derivative under modest pressure, see: Org. Synth. Coll., 5, 670 (1973).

Rhodium catalysts have also been used for the reduction of oximes to amines.
