Abstract
Metal catalysts comprising hollow forms or spheres are made of metal alloy and optionally activated. The metal catalysts can be used for the hydrogenation, dehydrogenation, isomerization reductive alkylation, reductive amination, and/or hydration reaction of organic compounds.
Claims11
A process for the hydrogenation, dehydrogenation, isomerization and/or hydration reaction of organic compounds comprising reacting said organic compounds in the presence of an activated Raney metal catalyst comprising hollow spheres, wherein said spheres have a shell which is impermeable.
A process for the hydrogenation of nitrobenzene comprising forming a reaction solution by mixing nitrobenzene and an inert organic solvent, suspending an activated Raney metal catalyst in said reaction solution, introducing hydrogen into said reaction solution and thereby carrying out a hydrogenation reaction.
A process for the dehydrogenation of an organic compound comprising reacting said organic compound with a dehydrogenation agent in the presence of an activated Raney metal catalyst in the form of hollow spheres.
A process for the isomerization of an organic compound comprising reacting said organic compound with an isomerization agent in the presence of an activated Raney metal catalyst in the form of hollow spheres.
A process for the hydration of an organic compound comprising reacting said organic compound with a hydration agent in the presence of an activated Raney metal catalyst in the form of hollow spheres.
