General description

Hexamethylenediamine (1,6-Diaminohexane) is a linear aliphatic diamine. It reacts with various inorganic acids to afford mono and diacid salts. It can be prepared from adipic dinitrile via catalytic hydrogenation reaction.
Hexamethylenediamine is a useful industrial intermediate widely used in the production of aliphatic and semi-aromatic polyamides. Analysis of 1,6-hexamethylenediamine (HDA) in aqueous solution, human urine and plasma by capillary gas chromatographic method with thermionic specific detection has been reported.

Application

Hexamethylenediamine (1,6-hexanediamine, HDA ) may be used in the preparation of the following:
  • polyamides and their hydrolytic and fungal degradability was investigated
  • mullite ceramics
  • dialkyl hexamethylene-1,6-dicarbamate (AHDC), via trans-esterification reaction of HDA and alkyl carbamates (AC) using FeCl3 as catalyst
