ABSTRACT
Isothermal vapor liquid equilibrium data for five binary systems including 1,1,2,3,3,3hexafluoro-1-propene and either 2,2,3,3,4,4,4-heptafluoro-1-butanol, cyclohexane, methylcyclohexane, 2-methyltetrahydrofuran or n-hexane were experimentally measured. The data were measured using the "static-analytic" method isothermally at 313.15 K and at pressures of (0.4 to 1) MPa. The expanded uncertainty for pressure and temperature were estimated to be 0.05 K and 0.007 MPa. On average, the expanded uncertainty for the liquid and vapor phase compositions were 0.008 and 0.002, respectively. The experimental data were correlated using the Peng-Robinson equation of state with the Mathias-Copeman alpha function and Wong-Sandler mixing rule. The Wong-Sandler mixing rule was coupled with the Non-Random Two-Liquid activity coefficient model.
