Versuchsvorschrift
It is known to prepare 1,4-bis(aminomethyl)cyclohexane from dicyanobenzene in a two stage process as disclosed, e.g., in DE-A 3,003,730. In the first stage dicyanobenzene is catalytically hydrogenated to produce 1,4-bis(aminomethyl)benzene, which is then catalytically hydrogenated to produce 1,4-bis(aminomethyl)cyclohexane. One disadvantage is that the starting material must be produced with hydrogen cyanide.
