Isothermal vapor-liquid equilibrium data of difluoromethane (HFC-32) +ethyl fluoride (HFC-161) mixture in the range of temperatures 253.15 K to 303.15 K have been measured in the wide range of compositions. The experimental method used for this work is the single-cycle type. Using Peng-Robinson (PR) equation of state, combined with the first Modified Huron-Vidal (MHV1) mixing rule and Wilson model, the vapor-liquid equilibrium data are correlated. The correlation results have a good agreement with the experiment results. The average absolute vapor composition deviation is within 0.0125, and its largest absolute deviation of the vapor composition is 0.0568; the average relative pressure deviation is within 0.76 % and its largest relative pressure deviation is 2.87 %. In addition, the results reveal that there is no azeotrope in the binary system, and their temperature glides are small.
