    Abstract: 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.

    Abstract: The invention relates to a method for producing a polyamide by converting a mixture containing a monomer that comprises a nitrile group and at least one additional functional group that is capable of forming a carboxamide group, in addition to water in the presence of titanium dioxide, which acts as the catalyst. Said method is characterised in that the titanium dioxide has a BE T surface area ranging between 5 and 35 m2/g, determined by means of a volumetric process according to a multipoint method, as per the German standard DIN 66 131.
