Isothermal vapour-liquid equilibrium data for the binary systems of CHF3 with (n-nonane, n-decane, or n-undecane) and C2F6 with (n-nonane or n-decane)

摘要

The isothermal vapour-liquid and vapour-liquid-liquid equilibria of five binary refrigerant + n-alkane systems at near ambient temperatures were measured using a static-analytic apparatus and a static synthetic apparatus. The phase equilibrium data for the systems of trifluoromethane (R-23) + n-nonane and hexafluoroethane (R-116) + n-decane were measured using the static-analytic apparatus, whereas bubble point data were measured with the static-synthetic apparatus for the systems of R-23 + n-decane, R-23 + n-undecane and R-116 + n-nonane. The temperatures that were investigated for these systems ranged between (272.9 and 323.1) K.
