As part of the USAF-sponsored halon replacement project,
solubility measurements of nitrogen and Freon-23 in
eleven potential halon replacement agents and
evaluations of the thermodynamic properties of the
agents are currently being conducted at NIST. The
eleven agents proposed by the USAF are: FC-31, FC-318,
HCFC-124, HFC-227, HFC134a, FC-218, HCFC-22, HFC-125,
HFC-236, FC-116, and HFC-32/HFC-125 azeotrope. The
determination of the solubility of nitrogen or Freon-23
(HFC-23) in the replacement agents is essential because
nitrogen or Freon-23 is being considered as a
pressurization gas; nitrogen is currently used in
existing halon 1301 bottles. The purpose of using the
pressurization gas is to expedite the discharge of the
agent and to increase the penetration distance of the
agent during discharge.
