Application

Hexamethylenediamine (HMDA) can be used as a reagent used to modify acrylonitrile copolymers and to polycondense with compounds such as calcein.
It can be used as a:
  • Reactant for the synthesis of dialkyl hexamethylene-1,6-dicarbamate with alkyl carbamate in the presence of various metal catalysts via the transesterification reaction.
  • Surface modifier for chlorinated and fluorinated nanodiamond synthesized by detonation.
  • Reactant with adipic acid for the synthesis of nylon 6-6 by polycondensation.
