WebThe use of supercritical fluids is spreading more and more throughout the world. The interest in them and their applications is clear from the increasing number of papers and patents in the last few years, as well as by the number of new research groups and facilities. A supercritical fluid (SCF) is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist, but below the pressure required to compress it into a solid. It can effuse through porous solids like a gas, overcoming the mass transfer limitations that slow liquid transport through such materials. SCF are much superior to gases in their ability to dissolve materials like liquids or solids.

WebJan 24, 2024 · The most commonly used supercritical fluid is CO 2. Its low critical temperature of 31.1 o C and its low critical pressure of 72.9 atm are relatively easy to achieve and maintain. Although supercritical CO 2 is a good solvent for nonpolar organics, it is less useful for polar solutes. WebA supercritical fluid (SCF) is a fluid above its critical temperature and pressure. It is characterized by physical properties (such as viscosity and diffusivity) that can be continuously varied between those of liquids and gases. The liquid-like density of a SCF is associated with its ability to dissolve solutes, and hence its solvent power.
