Supercritical fluid - Wikipedia

The advantages of ,supercritical fluid extraction, (compared with liquid ,extraction,) are that it is relatively rapid because of the low viscosities and high diffusivities associated with ,supercritical, fluids. The ,extraction, can be selective to some extent by controlling the density of the medium, and the extracted material is easily recovered by ...
