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.
Claims2
A process for the production of a Raney copper catalyst with an average particle size of from 5 μm to 65 μm, which is doped with at least one metal selected from the group consisting of iron and/or noble metals, wherein a copper/aluminum alloy is activated with an aqueous sodium hydroxide solution, the catalyst is washed, suspended in water, an iron salt or noble metal salt solution is added to the suspension, the pH is adjusted to a value of from 4 to 11, and the catalyst is separated from the solution and washed.
