Isothermal P‐x data for the binary system ethylene‐propane were measured at four temperatures by means of a total pressure apparatus. Equilibrium vapor compositions were calculated with the supporting properties obtained from the Clausius Equation of state. In the calculation, the parameters of the Clausius Equation were considered to be temperature‐dependent. The validity of the apparatus and the proposed method of calculation was established by comparing satisfactorily phase equilibrium values obtained in this study with those reported in the literature for the binary systems argon‐nitrogen and argon‐methane. In addition, several vapor compositions were also determined experimentally for the binary system ethylene‐propane to confirm the accuracy of the calculated results.
