221	The determination of solubility of liquids in supercritical fluids using dielectric constants Wabula, Kazamwali Serge. January 2011 (has links) M. Tech. Chemical Engineering. / The solubility of highly volatile non polar solutes (hexane, toluene and benzene) was determined in CO2, in the vicinity of supercritical conditions using a method employing dielectric constants. This method is based on the measurement of the dielectric constant of the saturated supercritical solution and that of the supercritical solvent as a function of pressure along different isotherms, by using the Clausius- Mossotti function. Results were in agreement with literature values, proving that this method can be used to determine the solubility of a solute in a pressurized gas. The results obtained demonstrate the capability of the dielectric constant method as a nonintrusive, simple and efficient means of determining accurately the solubility of liquids in supercritical solvents.
