Isothermal vapor liquid equilibrium (VLE) data were measured for the 1,1-difluoroethane (HFC- 152a) + isobutene system in the temperature range from 273.15K to 348.15K at 15K intervals. The experiments were carried out with circulating-type apparatus with on-line gas chromatography. The VLE data were well correlated by the Peng Robinson Stryjek Vera equation of state with theWong Sandler mixing rules involving NRTL model, and the results show a positive azeotrope at each temperature.
