Abstract:
Raney copper which is doped with at least one metal from the group comprising iron and/or noble metals is used as a catalyst in the dehydrogenation of alcohols.
Abstract:
Fixed-bed Raney-type catalysts are made from metal alloy fibers and/or flakes previously fabricated according to the crucible metal extraction method and then tablated, pressed in mats and/or located into a cartridge. The catalysts are used for the hydrogenation, dehydrogenation, isomerization, reductive alkylation, reductive amination, and/or hydration of organic compounds.
Abstract:
A process for preparing and passivating Raney nickel from a 50:50 aluminum-nickel alloy. The aluminum-nickel alloy is etched to form Raney nickel. The Raney nickel is then suspended in water and introduced to oxygen bubbled into the suspension thereby passivating the Raney nickel.
Abstract:
Raney copper, which is doped (promoted) with an effective quantity of a doping (promoting) agent selected from the group boric acid, onium fluorides, salts of fluorine complex anions, and heteropoly acids, represents an outstanding oxidation catalyst for amine-group-containing primary amines to carboxylic acids.
