Abstract (en)
[origin: WO2007031488A2] The invention relates to a method for the hydrogenation of oligonitriles comprising at least two nitrile groups, in the presence of a catalyst, which is pre-treated by being brought into contact with a compound A prior to the hydrogenation process, said compound being selected from the following: alkaline metal carbonates, alkaline-earth metal carbonates, ammonium carbonate, alkaline metal hydrogencarbonates, alkaline-earth metal hydrogencarbonates, ammonium hydrogencarbonate, alkaline-earth metal oxocarbonates, alkaline metal carboxylates, alkaline-earth metal carboxylates, ammonium carboxylates, alkaline metal dihydrogen phosphates, alkaline-earth metal dihydrogen phosphates, alkaline metal hydrogen phosphates, alkaline-earth metal hydrogen phosphates, alkaline metal phosphates, alkaline-earth metal phosphates and ammonium phosphate, alkaline metal acetates, alkaline-earth metal acetates, ammonium acetate, alkaline metal formiates, alkaline-earth metal formiates, ammonium formiate, alkaline metal oxalates, alkaline-earth metal oxalates and ammonium oxalate.
