Characteristics
and uses of supercritical waterA supercritical fluid possesses the characteristics of both
fluid and gaseous substances: the fluid behavior of dissolving
soluble materials, and the gaseous behavior of excellent diffusibility.
In the case of supercritical water particularly, the effect as
a reaction-causing solvent is great, and because continuous control
over the physical properties of fluid is allowed by regulation
of the pressure and/or the temperature, various uses in the field
of reacting systems are being considered.
Synthesis of artificial crystal (which uses the difference between the solubility in an intense solvent action under conditions of both high temperature and high pressure), has been in use for some time as an industrial application of supercritical water as a reaction solvent; more recently, supercritical water with its special physical properties has been applied in the wide area of organic substance reactions.
