| 发明名称 | Process for hydrogenating nitriles | ||
| 摘要 | The present invention relates to a process for hydrogenating nitriles by means of hydrogen in the presence of a catalyst in a reactor, where the catalyst is arranged in a fixed bed, wherein the cross-sectional loading in the reactor is in the range from 5 kg/(m2 s) to 50 kg/(m2 s). 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. | ||
