An experimental setup which allows measuring the solubility of solids and liquids in supercritical (SC) fluids in a wide range of temperatures and pressures using a dynamic method is constructed. Experimental data on the solubility of anthracene at 318.1 and 328.1 К and results on the solubility of ibuprofen at 313, 323, and 333 K and 10—30 MPa are obtained. Solubility of ibuprofen in SC-CO2 is described using the Peng — Robinson equation of state. Parameters of binary interactions for the system «ibuprofen — supercritical CO2» are obtained.
