Hexamethylenediamine or 1,6-hexanediamine is a diamine with a hexamethylene hydrocarbon chain and amine functional groups at each end. It has a strong amine odor, similar to piperidine. Hexamethylenediamine is produced from adiponitrile.
Its main uses are as a raw material in the
- production of nylon polymers
- production of hexamethylene diisocyanate (HDI) for use as monomer feedstock in polyurethane production
- cross-link agent in epoxy resins.
Hexamethylenediamine is highly toxic and can cause serious injuries. These include burns and severe irritation. Such injuries were observed in the major accident that occurred at the BASF site in Seal Sands, near Billingham on 4 January 2007 where 16 people were treated for serious injuries and one for burns. In total, 37 people were reported to have been injured as a result of the accident.
Hexamethylenediamine is stable, but combustible. It is incompatible with strong oxidizing agents, strong acids, and organic materials.
