Hexamethylenediamine or hexane-1,6-diamine, is the organic compound with the formula H 2 N(CH 2) 6 NH 2. The molecule is a diamine, consisting of a hexamethylene hydrocarbon chain terminated with amine functional groups. The colorless solid (yellowish for some commercial samples) has a strong amine odor.
In terms of quantities produced, 1,6-diaminohexane (a precursor to Nylon 6-6) is most important, followed by ethylenediamine. [2] Vicinal diamines (1,2-diamines) are a structural motif in many biological compounds and are used as ligands in coordination chemistry .

In a two-step hydrogenation process with a metal catalyst – first at 60 °C then at 180 °C – 1,6-hexanediol is mainly obtained via several intermediates. [ 15 ] 1,6-hexanediol can be used as a starting material for the production of polyesters , polyurethanes and diamine 1,6-diaminohexane .
2-Methylene glutaronitrile is a side-product in the production of hexanedinitrile which is used (after hydrogenation to 1,6-diaminohexane) as a key component for engineering polymers such as the polyamides (PA 66) or polyurethanes. Hexanedinitrile can be industrially produced by electrochemical hydrodimerisation or by catalytic dimerization of ...
