<p>Hydrogenation of oligonitrile with at least two nitrile groups in the presence of a catalyst, which is pre-treated by contacting with a compound A, before the hydrogenation process; where the compound A is e.g. alkaline metal carbonates, alkaline-earth metal carbonates, ammonium carbonate, alkaline metal hydrogencarbonate, alkaline-earth metal hydrogencarbonate, ammonium hydrogencarbonate and alkaline-earth metal oxycarbonate. Hydrogenation of oligonitrile with at least two nitrile groups in the presence of a catalyst, which is pre-treated by contacting with a compound A, before the hydrogenation process; where the compound A is alkaline metal carbonates, alkaline-earth metal carbonates, ammonium carbonate, alkaline metal hydrogencarbonate, alkaline-earth metal hydrogencarbonate, ammonium hydrogencarbonate, alkaline-earth metal oxycarbonate, alkaline metal carboxylate, alkaline-earth metal carboxylate, ammonium carboxylate, alkaline metal dihydrogen phosphate, alkaline-earth metal dihydrogen phosphates, alkaline metal hydrogen phosphates, alkaline-earth metal hydrogen phosphates, alkaline metal phosphates, alkaline-earth metal phosphates, ammonium phosphate, alkaline metal acetates, alkaline-earth metal acetates, ammonium acetate, alkaline metal formate, alkaline-earth metal formate, ammonium formate, alkaline metal oxalates, alkaline-earth metal oxalates or ammonium oxalate. Independent claims are also included for: (1) an oligo amine or amino nitrile, obtained from an oligo nitrile; (2) a catalyst comprising a metal from group VIII to X, which are pretreated with the compound A, where the cobalt or nickel catalyst is pre-treated with compound A excluding alkali metal carbonate or alkali metal hydrogen carbonate; and (3) a method for preparing the catalyst comprising treating a metal form group VIII to X with the compound.</p> |
