    摘要: Hydrogen peroxide production by oxidation of a 2-alkyl-9,10-dihydroxyanthracene, especially the 2-(t-butyl) compound, and catalytic hydrogenation of the resulting 2-alkylanthraquinone back to the dihydroxy compound, using a water-insoluble (bipyridyl) rhodium complex as hydrogenation catalyst. Especially such process carried continuously in a cell in which an organic phase is separated by a porous membrane from an aqueous phase, and the anthraquinone is hydrogenated on the organic side of the cell and hydrogen peroxide is obtained from the aqueous phase. Preferably the rhodium complex is formed with a bipyridyl ligand attached to polystyrene beads, whereby to assure that rhodium is not carried into the hydrogen peroxide production side of the cell.

    摘要: A new liquid phase oxidation process in which a metal nitro complex transfers an oxygen atom from the nitro ligand to a substrate; especially such process conducted cyclically or catalytically using molecular oxygen as the oxygen source. Metal nitrosyl complex is formed as a coproduct together with an oxidation product of the substrate. In a catalytic process, molecular oxygen maintains a concentration of nitro ligand in the reaction mixture. In a cyclic process, nitrosyl ligand of the metal nitrosyl coproduct is reoxidized by molecular oxygen in presence of a monodentate base such as pyridine to nitro ligand; and the nitro complex, thus regenerated, can be used again to oxidize the substrate, In particular the metal is a Group VIII metal, especially cobalt and the nitro complex is pyridine cobalt nitro saloph. To accelerate oxidation of the substrate at given temperature, a cocatalyst is included in the reaction mixture, e.g. an organic complex of a transition metal such as Mo(VI), Pd(II), or a compound of a trivalent metallic element with an element of Group VII, such as the compound BF.sub.3.

    摘要: A novel process is described for preparing low valent Group VIII metal hydrides, useful as catalysts in the hydrogenation of a large variety of organic compounds, in which a low valent Group VIII metal halide complex, such as (Ph.sub.3 P).sub.3 RhCl, is reacted with an alkali or alkaline earth metal alkylamide, such as LiN(CH.sub.3).sub.2, containing at least one alkyl group having an alkyl hydrogen atom in the beta position with respect to the metal atom. The metal alkylamide functions both as a dehalogenating and hydrogenating agent in the process. The process can be conducted at room temperature in a suitable organic solvent under an inert atmosphere utilizing the metal alkylamide in stoichiometric quantities. The process is also useful in preparing zero valent Group VIII metal complexes, such as (Ph.sub.3 P).sub.4 Pd.degree..
