The Journal of Supercritical Fluids is an international journal devoted to the fundamental and applied aspects of pressurized substances and mixtures in the fluid state especially at conditions above the critical point including reactions, separations and chemical processes.

Supercritical fluid extraction is known to be dependent on the density of the fluid that in turn can be manipulated through control of the system pressure and temperature. The dissolving power of a SCF increases with isothermal increase in density or an Isopycnic (constant density) increase in temperature.

Supercritical Fluids A fluid is in “supercritical state” when it is placed at a temperature above its critical temperature and at a pressure above its critical pressure. Above these conditions there is no frontier between liquid and gas, and small changes in the temperature or pressure could result in continuous changes in the fluid’s density, solvent power and other physical properties. Supercritical fluids combine useful properties of gas and liquid phases, as it can behave like both a gas and a liquid in terms of different aspects. A supercritical fluid provides a gas-like characteristic when it fills a container and it takes the shape of the container.

Supercritical Fluid Extraction and High Performance Liquid Chromatography Determination of Carbendazim in Bee Larvae, Jose L. Bernal, Juan J. Jimenez, and Maria T. Martin. Supercritical fluid extraction (SFE) has become one of the most popular green extraction techniques nowadays since it has demonstrated many advantages compared with traditional or classical Supercritical Fluid Group - UNISA, Fisciano (SA).

This particular behavior of substances was first observed in 1822 by French engineer and physicist, Charles Cagniard de La Tour in his famous cannon barrel experiment. The structure of the supercritical fluid is discussed. The unusual solvent properties of supercritical fluids are explained within the framework of binary fluid phase diagrams, including a solid solute.

Viscosity for a supercritical fluid is almost the same to a gas and it is 10 times less than a .

It is a substance which can be either liquid or gas, used in a state above the critical temperature and critical pressure where gases and liquids can coexist. Supercritical Fluid Extraction: a Primer Supercritical CO2 has so many advantages that it is now used world wide to extract compounds from a huge variety of materials.
