| 摘要 | A supported catalyst containing ruthenium and another platinum group metal are used to hydrogenate organic compounds, numerous examples of which are given. Specified supports are C, Al2O3, SiO2, Kieselguhr, silicon gel, TiO2, CoCO3, BaSO4 and bentonite. Specified other platinum group metals are Pt, Pd and Rh. The ruthenium may be present in the catalyst as the oxide or alternatively (having been reduced) as the metal itself. Examples are given. Compounds which may be hydrogenated include benzene, toluene, xylene, naphthalene, and anthracene.ALSO:In a process for hydrogenating a compound selected from carboxylic aromatic, heterocyclic aromatic, aliphatic nitro, aromatic nitro, nitrile, acetylenic diol, phenols, alkoxybenzenes, aromatic carboxylic acids, amines, hydroxyl amines, oximes and imines, the compound is contacted with a supported catalyst containing ruthenium and another platinum group metal. Specified compounds are benzene, toluene, xylene, naphthalene, anthracene, pyridine, pyrrole, furan, furfuryl alcohol, 1-nitropropane, 2-nitropropane, b -nitroethyl benzene, nitrobenzene, nitrotoluenes, nitrophenols, nitronaphthalenes, propionitrile, benzyl cyanide, acetonitrile, acrylonitrile, phenyl cyanide, toluonitrile, naphthyl cyanide, butyne-2-diol 1 : 4, 1 : 4 dimethylbutyne-2-diol 1 : 4, 3 : 6 dimethyloctyne-4-diol 3 : 6, 1 : 4 diethylbutyne-2-diol-1 : 4, phenol, cresols, naphthols, anthranols, methoxybenzenes, methoxyphenols, ethoxybenzenes, methoxytoluenes, benzoic acid, toluic acid, ethoxy-benzoic acid and naphthoic acid, aniline, N-methylaniline, N : N dimethylaniline, naphthylamine, b -ethyl phenylamine, phenylhydroxylamine, naphthylhydroxylamine, butylhydroxylamine, cyclohexanone oxime, salicylaldehyde oxime, 1-phenyl-1-2 propanedione-2-oxime and N-ethyl ethylimine (CH3.CH=N.C2H5). Examples describe the hydrogenation of and | ||||||
