This work presents new experimental phase equilibrium data of mitotane in supercritical CO2 and mitone in supercritical CO2 plus ethanol. The synthetic-static method in a high-pressure variable-volume view cell was used to measure the solid-fluid (SF) and the fluid-fluid (F) equilibrium data. The phase equilibrium experiments were determined in temperature ranging from (298 to 333) K and pressure ranging from (34.4 to 218.4) bar. The Peng Robinson equation of state was used for describing the fluid phases and an expression for the fugacity of pure mitotane solid was used to model the SF and FF equilibrium data for these mixtures. Fair agreement was found between experimental and calculated values.
