Solid-supercritical fluid phase equilibria Benjamin C.-Y. Lu and Dingan Zhang Department of Chemical Engineering, University of Ottawa, Ottawa, Ontario, Canada, K1N 984 Abstract - Different types of phase behavior observed in binary mixtures containing a solid and a supercritical fluid … A supercritical fluid is any substance at a temperature and pressure above its thermodynamic critical point. It can diffuse through solids like a gas, and dissolve materials like a liquid. Additionally, close to the critical point, small changes in pressure or temperature result in large changes in density, allowing many properties to be "tuned".

• Viscosity is lower so very useful for compound which have no functional group, as detection method in HPLC fails.

In theory, the supercritical region can be reached in two ways: Increasing the pressure above the Pc value of the material while keeping the temperature stable and then increasing the temperature above Tc value at a stable pressure value. Since supercritical fluids don't undergo a phase change, they can't bubble, it would be an added safety feature for nuclear reactors. Baron Charles Cagniard de la Tour discovered supercritical fluids in 1822 while conducting experiments with the discontinuities of the sound of a flint ball in a sealed cannon barrel filled with various fluids at However if we move from the liquid to the supercritical fluid by increasing the temperature, as shown by the arrow in this diagram: then we measure neither a first or second phase transition. The system changes continuously.

. Consider the behavior of the system which is heated at the pressure, that is higher than the critical press This single phase is called a supercritical fluid, which exhibits many of the properties of a gas but has a density more typical of a liquid. For example, the density of water at its critical point ( T = 374°C, P = 217.7 atm) is 0.32 g/mL, about one-third that of liquid water at room temperature but much greater than that of water vapor under most conditions. Use phase diagrams to identify stable phases at given temperatures and pressures, and to describe phase transitions resulting from changes in these properties.
