ABSTRACT
tIn 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-1and 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 volumecell. The liquid vapor transitions were classified as a bubble points and dew points in the presence orabsence of solid phase. The experimental vapor liquid equilibrium data were satisfactory correlatedusing the Peng-Robinson equation of state with a quadratic mixing rule.
