ABSTRACT
The isothermal vapour-liquid equilibrium (VLE) data for two hexafluoroethane (R-116)/nalkane systems were each measured at two temperatures of 288 K and 297 K. The two nalkanes of interest are n-pentane and n-hexane. The pressures which were measured ranged from (0.017 to 7.040) MPa. A "static-analytic" VLE apparatus, equipped with pneumatic (Rapid Online Sampler-Injector) ROLSI(R) capillary samplers, was used to perform the measurements. The ROLSI(R) gives this apparatus the capability of sampling both the liquid and the vapour phases, without significant equilibrium perturbation with respect to the estimated analytical uncertainties. Vapour-liquid-liquid equilibria and liquid-liquid equilibria were experienced at R-116 compositions close to unity for the R-116 and n-hexane system.
