Vapor–liquid equilibria of the (hexafluoroethane D 1,1,1-trifluoroethane) binary system from 258 to 343 K up to 3.89 MPa

Abstract : Development of modern refrigeration systems is critical for the success of new global environmental protection efforts. The binary system of refrigerants: Hexafluoroethane (R116) þ 1,1,1-trifluoroethane (R143a), has been studied with the aim of providing PTxy data. Isothermal vapor–liquid equilibrium data have been generated using the ‘‘static– analytic'' method from 258 to 328K at pressures from 0.39 to 3.89MPa. The model composed of the Peng–Robinson equation of state, the Mathias–Copeman alpha function, the Wong–Sandler mixing rules and the NRTL cell theory is applied herein to correlate the data and calculate the critical line.
