Abstract
The solvent polarity parameters, including the dipolarity/polarizability π* parameter, hydrogen-bond donor acidity α parameter, and hydrogen-bond acceptor basicity β parameter, were measured for supercritical carbon dioxide and cosolvent systems with ethanol, 2,2,2-trifluoroethanol, and dimethyl sulfoxide at pressures of 9.81—27.95 MPa and 318 K. A linear correlation was examined for relating those parameters with each other.Keywords
