Isophoronenitrile (130 ml/h), ammonia (600 g/h) and 300 l/h of hydrogen are passed at about 80–100° C. in the upflow mode through the first reactor (imination reactor, 200 ml) charged with γ-Al2O3 as catalyst. The imination occurs here. The reaction mixture is fed into the first reactor (trickle-bed reactor) containing the cobalt catalyst. The temperature there is 90° C. In the third (last) reactor, the after-hydrogenation is carried out at 130° C. in the upflow mode in the presence of the cobalt catalyst. The product mixture is depressurized and cooled and analyzed by gas chromatography.
