Supercritical fluids as solvents for chemical and materials processing

Charles A. Eckert, Barbara L. Knutson & Pablo G. Debenedetti

Fluids near their critical point have dissolving power comparable to that of liquids, are much more compressible than dilute gases, and have transport properties intermediate between gas-and liquid-like. This unusual combination of physical properties can be advantageously exploited in environmentally benign separation and reaction processes, as well as for new kinds of materials processing.
