The invention relates to a method for hydrogenating aliphatic alpha-, omega- dinitriles in the presence of a heterogeneous fixed-bed catalyst. The method is characterised in that the reaction mixture contains 2 µmol to 30 mmol Na, K, Rb, Cs, Mg, Ca, Sr, Ba or Mn or mixtures thereof in the form of a basic salt, in relation to 10 mol of the aliphatic alpha-, omega-dinitrile used.
L'invention concerne un procédé d'hydrogénation de dinitriles alpha,oméga aliphatiques en présence d'un catalyseur en lit fixe hétérogène. Ce procédé est caractérisé en ce que le mélange réactionnel contient 2 µmol à 30 mmol de Na, K, Rb, Cs, Mg, Ca, Sr, Ba ou Mn ou de leurs mélanges sous forme de sel basique par rapport à 10 mol des dinitriles alpha, oméga aliphatiques utilisés.
