چکیده
Supercritical Fluid properties are of interest as being significantly different from liquids or gases in the area near the critical temperature, T c , and the critical pressure, P c. The primary physical feature of supercritical fluids in the immediate critical point region is the very pronounced change in density with pressure. Critical region shown for carbon dioxide in terms of Pr and Tr, the reduced properties. CO 2 is the most common supercritical solvent and the one for which we have the most information.

Simulation of Separation of a Racemic Mixture of Ibuprofen by Supercritical Fluid Chromatography in Simulated Moving Bed
Separation of a racemic mixture of ibuprofen at a low concentration level by supercritical fluid chromatography in a simulated moving bed (SFC-SMB) is investigated by simulation. The feasibility of ibuprofen enantiomers separation has been experimentally examined in the literature. Our simulation results show that separation of ibuprofen enantiomers is feasible by this method, and R-ibuprofen a...
متن کاملForensic applications of supercritical fluid extraction and chromatography
The gas-like mass transfer properties and liquid-like solvation characteristics of supercritical fluid make it a promising medium in performing extractory and chromatographic separations, i.e., supercritical fluid extraction (SFE) and supercritical fluid chromatography (SFC), respectively. The tunable solvation properties of supercritical carbon dioxide not only improve SFE's efficiency and spe...
