Abstract: The present invention relates to a process for hydrogenating organic nitriles by means of hydrogen in the presence of a catalyst in a reactor, where the shaped body catalyst is arranged in a fixed bed, wherein the shaped body in the shape of spheres or rods has in each case a diameter of 3 mm or less, in the shape of tablets a height of 4 mm or less, and in the case of all other geometries in each case has an equivalent diameter L = 1/a' of 0.70 mm or less, where a' is the external surface area per unit volume (mms 2/mmp 3), with: (I) where Ap is the external surface area of the catalyst particle (mms 2) and Vp is the volume of the catalyst particle (mmp 3). The present invention further relates to a process for preparing downstream products of isophoronediamine (IPDA) or N,N-dimethylaminopropylamine (DMAPA) from amines prepared according to the invention.
