Abstract
Amine compounds, more particularly diamine compounds, are prepared by hydrogenating compounds including nitrile functions. The preparation can include the use of a hydrogenation catalyst, adapted for the hydrogenation of nitrile compounds into amine compounds, including Raney nickel as well as iron, chromium, and zinc as doping elements.
