Vapor liquid equilibrium data for the difluoromethane (R32) dimethyl ether (RE170) system at temperatures from 283.03 to 363.21K and pressures up to 5.5MPa
Isothermal vapour liquid equilibrium data have been measured for the R32 + RE170 binary system at seven temperatures between 283.03 and 363.21 K, and pressures between 0.5 and 5.5MPa. The experimental method used in this work is of the static-analytic type, taking advantage of two pneumatic capillary samplers (RolsiTM, Armines patent) developed in the CEP/TEP laboratory. The data were obtained with uncertainties within +-0.02 K, +-0.0002MPa and +-1% for molar compositions. The isothermal P, x, y data are well represented with the Peng and Robinson equation of state using the Mathias Copeman alpha function and the Wong Sandler mixing rules involving the NRTL gE model.
