Supercritical Water as a Solvent
Angewandte Chemie - International Edition, 2005AbstractWater is not restricted to moderate temperatures and low pressures, but can exist up to very high temperatures, far above its critical point at 647 K. In this supercritical regime, water can be gradually compressed from gas‐like to liquid‐like densities.

Supercritical Transitiometry of Polymers
Analytical Chemistry, 1998Employing supercritical fluids (SCFs) during polymers processing allows the unusual properties of SCFs to be exploited for making polymer products that cannot be obtained by other means. A new supercritical transitiometer has been constructed to permit study of the interactions of SCFs with polymers during processing under well-defined conditions of ...

Solvation in supercritical water
The Journal of Chemical Physics, 2006Solvation in supercritical water under equilibrium and nonequilibrium conditions is studied via molecular dynamics simulations. The influence of solute charge distributions and solvent density on the solvation structures and dynamics is examined with a diatomic probe solute molecule. It is found that the solvation structure varies dramatically with the

Supercritical impregnation of polymers
Current Opinion in Solid State and Materials Science, 2003The interest in the supercritical fluid impregnation of polymeric materials stems from the opportunity to utilize high diffusivity, low surface tension and the ease of solvent recovery for the preparation of new polymeric materials. This term includes a wide range of applications of the supercritical impregnation process that will be discussed in this ...

Supercritical fluid processing
Environmental Science & Technology, 1986Separation and detoxification reactions often can be run advantageously using supercritical fluids (SCFs) as processing media. The use of a supercritical solvent frequently permits extraction of very dilute toxic species, either directly or in a two-step process.

Amphiphiles for supercritical CO2
Biochimie, 2012A semi-fluorinated hybrid amphiphile, pentadecafluoro-5-dodecyl (F7H4) sulfate, has been shown to form reversed micelles in dense CO(2); the aggregates evolve to form water-in-CO(2) (w/c) microemulsion droplets on addition of water. Aggregation structures in these w/c phases have been characterised by small-angle neutron scattering (SANS), showing the ...

Simulation of supercritical water and of supercritical aqueous solutions
The Journal of Chemical Physics, 1991Molecular dynamics (MD) calculations have been performed to determine equilibrium structure and properties of systems modeling supercritical (SC) water and SC aqueous solutions at two states near the critical point using the simple point charge (SPC) potential model of Berendsen et al. for water.

Chromatography with Supercritical Fluids
Science, 1987In supercritical fluid chromatography (SFC) the mobile phase is neither a gas nor a liquid, but is a supercritical fluid. As a result of the unique properties of supercritical fluids, SFC is rapidly becoming a prominent separation technique for the analysis of reactive, thermally labile, and nonvolatile compounds.
