Title: Solubilities of Nitrogen and Freon-23 in Alternative Halon Replacement Agents
Published: May 11, 1993
Abstract: 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.
