Experimental Measurements and Modeling of Vapor-Liquid Equilibria for Eight Mixtures Containing trans-1-Chloro-3,3,3-trifluoropropene (R1233zd(E)) and 2-Chloro-3,3,3-trifluoropropene (R1233xf)

Isothermal vapor-liquid equilibria (VLE) for eight binary systems involving R1233zd(E) [R1233zd(E) + n-butane, R1233zd(E) + CO2, R1233zd(E) + HCl, R1233zd(E) + R134a, R1233zd(E) + R152a, R1233zd(E) + R245fa], and R1233xf (R1233xf + R134a, R1233xf + R152a, R1233xf + R245fa) were measured at temperatures from 263 to 353 K. The experiments were conducted by means of a static analytic apparatus with phase analysis via gas chromatography, with the resulting maximum expanded uncertainties of 0.2 K for temperatures, 10 kPa for pressure, and 0.04 for vapor and liquid mole fractions. The main advantage of the equipment is that vapor and liquid samples were taken from vapor and liquid phase by two capillary samplers (ROLSI (R)). The Peng-Robinson equation of state and a modified Patel-Teja equation of state were both considered to represent the experimental data. If possible, comparison between the new experimental data and prediction with REFPROP 10.0 software were realized.
