An apparatus based on the “static–analytic” method, equipped with a movable rapid online sampler–injector (ROLSI), was used to undertake the measurements. The combined expanded uncertainties are estimated at 0.11 K, 4 kPa, and 0.012 and 0.009 for the temperature, pressure, and the equilibrium liquid and vapor mole fractions, respectively. The experimental data were correlated with the Peng–Robinson equation of state using the Mathias–Copeman α function, together with the Wong–Sandler mixing rule utilizing the nonrandom two-liquid activity coefficient model.enThis document is the Accepted Manuscript version of a Published Work that appeared in final form in Journal of Chemical and Engineering Data, © 2015 American Chemical Society after peer review and technical editing by the publisher.Isothermal vaporLiquid equilibrium dataExperimental dataPostprint Article
