Abstract (en)
[origin: WO2007068631A1] The invention relates to a method for hydrogenating oligonitriles containing at least two nitrile groups in the presence of a catalyst which is pre-treated by being contacted with a compound A prior to the hydrogenation process, said compound A being selected among alkali metal carbonates, alkaline earth metal carbonates, ammonium carbonate, alkali metal hydrogen carbonates, alkaline earth metal hydrogen carbonates, ammonium hydrogen carbonate, alkaline earth metal oxocarbonates, alkali metal carboxylates, alkaline earth metal carboxylates, ammonium carboxylates, alkali metal dihydrogen phosphates, alkaline earth metal dihydrogen phosphates, alkali metal hydrogen phosphates, alkaline earth metal hydrogen phosphates, alkali metal phosphates, alkaline earth metal phosphates and ammonium phosphate, alkali metal acetates, alkaline earth metal acetates, ammonium acetate, alkali metal formates, alkaline earth metal formates, ammonium formate, alkali metal oxalates, alkaline earth metal oxalates, and ammonium oxalate.
