Abstract
The use of supercritical fluids has been developed in a wide range of techniques and processes including drug, cosmetics, and food industry. The bubble points of dichloromethane + supercritical carbon dioxide (CO2) system were measured at temperature from 303.2 to 328.2 K and the cloud points of poly(vinyl pyrrolidone) (PVP) + dichloromethane + supercritical CO2 system were measured at temperature ranging from 313.13 to 363.33 K and pressure up to 25.5 MPa. Phase behavior of experimental data could be correlated satisfactorily with the quasi-chemical nonrandom lattice fluid (QLF) equation of state by introducing temperature-dependent binary interaction parameters.
