ABSTRACT:
The invention relates to a method for the selective hydrogenation of a dinitrile compound in the presence of a catalyst which comprises a metal of group 8 of the periodic system of the elements, the catalyst comprising a zeolite having a pore diameter of between 0.3 and 0.7 nm. The zeolite preferably has a structure chosen from the structures: ABW, AEI, AFT, ANA, ATN, ATV, ATT, AWW, BIK, CAS, CHA, DDR, EAB, EDI, ERI, GIS, JBW, KFI, LEV, LTA, MER, NAT, PHI, RHO, THO, YUG.
