Abstract :
In this work the vapor–liquid equilibrium for the {CO2(1) + dichloromethane(2) + medroxyprogesterone(3)} system were measured for different concentrations of medroxyprogesterone in dichloromethane (0.01 g mL−1 and 0.02 g mL−1) at temperatures ranging from (303 to 333) K and pressure up to 8.6 MPa. The experimental data were obtained using a visual synthetic static method employing a variable volume cell. The liquid–vapor transitions were classified as a bubble points and dew points in the presence or absence of solid phase. The experimental vapor–liquid equilibrium data were satisfactory correlated using the Peng–Robinson equation of state with a quadratic mixing rule.
