Procedimiento para la hidrogenación de nitrilos

摘要

The invention relates to a method for hydrogenating nitriles with hydrogen in the presence of a catalyst in a reactor, said catalyst being arranged in a fixed bed. The invention is characterized in that the cross-sectional load in the reactor ranges from 5 kg/(m2 s) to 50 kg/(m2 s). The invention further relates to a method for producing secondary products of isophorondiamine (IPDA) or N,N-dimethylaminopropylamine (DMAPA) from amines produced according to the invention.
