Application

Tetrahexylammonium bromide can be used:
  • As a hydrogen bond acceptor in the preparation of deep eutectic solvents which can be used for desulfurization and denitrogenation from n-heptane.
  • To produce aqueous biphasic system for the heavy metal ions preconcentration.
  • As a phase transfer salt to fabricate an optical chemical gas-sensor.
