Abstract

Organic nitro compounds are catalytically hydrogenated in an aqueous system with the aid of a concentrated noble metal catalyst deposited on an inert support, which has been diluted with an oleophilic carbon having an oil absorption factor of at least 200. The noble metal may be deposited on the support at a concentration of at least 2 per cent by weight and then diluted with the oleophilic carbon to a concentration of 0.01-1 per cent. Suitable carbons are those prepared from e.g. acetylene, i.e. "Furnace Blacks," which are non-porous. Suitable inert catalyst supports are carbon, diatomaceous earth or silica. The catalysts may be activated with e.g. oxides or hydroxides of iron, nickel, cobalt, aluminium, magnesium, manganese, chromium, vanadium or tungsten, or fluorides of boron and silicon as well as mixtures of these. Specific preparations mentioned are cyclohexylamine from nitrocyclohexane, b -amino-naphthalene from b -nitro-naphthalene, 5-aminoquinoline from 5-nitroquinoline, 1,5-diaminonaphthalene from 1,5-dinitronaphthalene, p-anisidine from p-nitro anisole, the amine of dinitrostilbene disulphonic acid from the corresponding sodium salt, p-aminobenzoic acid from p-nitro benzoic acid sodium salt and p-aminophenol from p-nitrophenol.ALSO:Catalysts for the hydrogenation of organic nitro compounds comprise a concentrated noble metal catalyst, e.g. platinum or palladium deposited on an inert support, which has been diluted with an oleophilic carbon having an oil absorption factor of at least 200. The noble metal may be deposited on the support at a concentration of at least 2 per cent by weight and then diluted with the oleophilic carbon to a concentration of 0.01 to 1 per cent. Suitable carbons are those prepared from acetylene, i.e. "Furnace Blacks," which are non-porous. Suitable inert catalyst supports are carbon, diatomaceous earth or silica. The catalysts may be activated with oxides or hydroxides of iron, nickel, cobalt, aluminium, magnesium, manganese, chromium, vanadium or tungsten or fluorides of boron and silicon, as well as mixtures of these.
