    摘要: Monolefins such as ethylene are reacted with ammonia using alkali metal amide catalysts such as cesium or rubidium amides, or low melting mixtures of amides such as cesium/potassium, cesium/sodium or sodium/potassium amides. Conversions are improved compared to reactions using sodium or potassium amide alone. Conversions of ethylene are improved also when liquid ammonia is present.

    摘要: A process is disclosed for reversibly absorbing acid gases from gaseous mixtures wherein a salt hydrate is heated to a temperature above its melting point and exposed to an acid gas which is absorbed by the salt hydrate to form a salt hydrate melt. This melt is thereafter cooled to a temperature sufficient to solidify the melt and to desorb the acid gas from the solidified salt hydrate. Preferred salt hydrates include tetramethylammonium fluoride tetrahydrate and tetraethylammonium acetate tetrahydrate.

    摘要: A novel class of heterogeneous catalysts, containing Group VIII transition metals in combination with alkali organic compounds is prepared, such as potassium naphthalene on ruthenium on carbon. The catalysts are useful as heterogeneous catalysts in the hydrogenation of carboxylic acid esters. A process for producing the materials is described. The catalysts permit the process of the hydrogenation of carboxylic acid esters to primary alcohols to be conducted with the ester in the liquid phase at a temperature not exceeding about 150.degree. C. with high selectivity. Catalysts of Group VIII transition metals and alkali metal on carbon are also useful in such processes.

    摘要: Processes are provided for the storage and release of hydrogen by means of a substantially reversible catalytic hydrogenation of extended pi-conjugated substrates which include large polycyclic aromatic hydrocarbons, polycyclic aromatic hydrocarbons with nitrogen heteroatoms, polycyclic aromatic hydrocarbons with oxygen heteroatoms, polycyclic aromatic hydrocarbons with alkyl, alkoxy, ketone, ether or polyether substituents, pi-conjugated molecules comprising 5 membered rings, pi-conjugated molecules comprising six and five membered rings with nitrogen or oxygen hetero atoms, and extended pi-conjugated organic polymers. The hydrogen, contained in the at least partially hydrogenated form of the extended pi-conjugated system, can be facilely released for use by a catalytic dehydrogenation of the latter in the presence of a dehydrogenation catalyst which can be effected by lowering the hydrogen gas pressure, generally to pressures greater than 0.1 bar or raising the temperature to less than 250° C. or less, or by a combination of these two process parameters.
