Measurement of Vapor-Liquid Equilibria for the Binary Mixture of Octafluoropropane and Hexafluoropropylene Oxide Containing Octafluorocyclobutane
Isothermal vapor liquid equilibrium (VLE) data were measured for the binary systems of octafluoropropane + octafluorocydo-butane and hexafluoropropylene oxide + octafluorocyclobutane system at the temperature range from 263.15 K to 303.15 K. The experiments were carried out with a circulating-type equilibrium apparatus including online gas chromatography analysis. The VLE data were correlated well by the Peng-Robinson equation of state using the Wong-Sandler mixing rules involving the NRTL model. All the binary parameters of these systems and the average absolute deviations (AADs) in terms of saturated pressure and vapor phase composition between the experimental and calculated values are represented.
