Title:
METHOD FOR HYDROGENATING ALIPHATIC ALPHA-, OMEGA-DINITRILES
Document Type and Number:
WIPO Patent Application WO1999044982
Kind Code:
A3
Abstract:
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 mu mol 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.
