Hexamethylenediamine has all the chemical properties of aliphatic amines.

With carbonyl compounds forms Schiff bases, with salts of Ag, Au, Cu, Pt and other metals - colored and hardly soluble complex compounds; enters into a cyanoethylation reaction; the action of NiO2 is oxidized to adipodinitrile.

Forms salts with carboxylic and mineral acids, for example. dihydrochloride (mp 258 ° C) and dihydrobromide (mp 263 ° C). Of great practical importance are the salts of hexamethylenediamine with dicarboxylic acids: adipate (mp 195 ° C) and sebacate (mp 172 - 173 ° C) - so-called. AG-salt and SG-salt, respectively.

When hexamethylenediamine interacts with phosgene, hexamethylene diisocyanate is formed.

Synonyms and international names

RUS: 1,6-diaminohexane, 1,6-hexanediamine
ENG: Hexemetheylene diamine, 1,6-Diaminohexane .1,6-Hexanediamine


Hexamethylenediamine forms salts with organic and inorganic acids. Salts of hexamethylenediamine, when heated with organic acids, are converted into amides of the corresponding acids.

This is used to obtain valuable polymer products based on hexamethylenediamine - polyamides (for example, nylon-66 by condensation with adipic acid).

Also generated from hexamethyleneamine, hexamethylene isocyanate is a valuable monomer in the production of polyurethanes. Diamine is also a cross-linking agent in the production of epoxy resins.
