Product Application of Hexamethylenediamine CAS#124-09-4

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
methoxycarbonylation of 1,6-hexanediamine with dimethyl carbonate to form dimethylhexane-1,6-dicarbamate.
Formation of high polymers, e.g., nylon 66.
dialkyl hexamethylene-1,6-dicarbamate (AHDC), via trans-esterification reaction of HDA and alkyl carbamates (AC) using FeCl3 as catalyst.
1,6-hexanediamine modified magnetic chitosan microspheres for fast and efficient removal of toxic hexavalent chromium.
