    摘要: Catalyst of cuprous chloride, as a first layer, on a carrier of particles of pyrogenic anhydrous silica or titania, or alpha-alumina produced from pyrogenic gamma-alumina, having as a second layer an alkali metal chloride especially KCl, and preferably also a rare earth metal chloride; especially LaCl.sub.3 ; formed by impregnation using non-aqueous solvents, especially CuCl in acetonitrile followed by KCl/LaCl.sub.3 in formic acid. The catalyst is effective at desirable reaction rates at temperatures well below 400.degree. C., such as 200.degree.-300.degree. C. and even below 200.degree. C., under certain conditions, for oxyhydrochlorination of organic materials such as methane; and is also effective for production of chlorine by the Deacon process at relatively low temperatures. Problems due to catalyst volatility and melting are substantially mitigated.

    摘要: The catalyst consists essentially of a calcium fluoride matrix and a thermally stable copper-containing phase as produced by coprecipitation of calcium fluoride and copper fluoride and/or calcium hydroxide and copper oxide, in presence of alkali metal or ammonium ion. The coprecipitate is thoroughly dried and heated at elevated temperature; followed, if the coprecipitate is in the form of hydroxide and/or oxide, by conversion of such hydroxide and oxide to fluoride.The preferred alkali metal ion is potassium.The most active and stable catalysts show by X-ray diffraction a pattern including lines characteristic of calcium fluoride and additional lines indicative of a face-centered cubic unit cell having unit dimension of about 8.1-8.4 A.The catalyst operates at about 200.degree.-550.degree. C. depending to some extent on the substrate.

    摘要: A process is disclosed for the preparation of metallic products from metal salts admixed with solvent wherein at least one of the metal salt and the solvent is easily reducible. The admixture is heated under hypercritical conditions of temperature and pressure to produce metallic products and a hypercritical fluid. The hypercritical fluid is subsequently removed from the reaction zone and the metallic product is collected. The metallic product includes pure metals selected from the group of silver, gold, platinum, palladium, ruthenium, rhodium, mercury, arsenic, rhenium, tellurium, iridium, osmium, and copper, and alloys and mixtures thereof. The metallic product ordinarily exists as finely divided powders which may be highly porous.
