Vapor-liquid equilibria of the binary systems nitrogen + bromotrifluoromethane, + bromochlorodifluoromethane, + 1,1,1,2,3,3,3-heptafluoropropane, and + trifluoroiodomethane from 293.2 to 313.2 K and 30 to 100 bar

Bromotrifluoromethane (halon-1301) and bromochlorodifluoromethane (halon-1211) have been used as clean, nontoxic, and effective fire extinguishing agents for a long time. But these compounds are being phased out because of their ozone-depletion potential. Isothermal vapor-liquid equilibria were measured in the binary systems nitrogen + bromotrifluoromethane, nitrogen + bromochlorodifluoromethane, nitrogen + 1,1,1,2,3,3,3-heptafluoropropane, and nitrogen + trifluoroiodomethane 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 Sandler mixing rule, and the relevant parameters are presented.
