Abstract

Isothermal solubilities of nitrogen in clean fire extinguishing agents, such as bromotrifluoromethane (Halon-1301), bromochlorodifluoromethane (Halon-121 t), 1,1,1,2,3,3,3- heptafluoropropane (HFC-227ea), and trifluoroiodomethane (FIC-13I1) were measured in a circulation-type equilibrium apparatus. The temperature range was (293.2 to 313.2) K and the pressure range was (30 to 100) bar. The experimental data were well correlated with the Peng- Robinson equation of state using the Wong and Sandier mixing rules, and the relevant parameters are presented.
