[edit] Uses
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.
[edit] Safety
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.[3][4] In total, 37 people were reported to have been injured as a result of the accident.
[edit] Stability
Hexamethylenediamine is stable, but combustible. It is incompatible with strong oxidizing agents, strong acids, and organic materials.
