| Abstract: | This review summarized the use of supercritical fluid (SCF) for extraction, chemical reaction and material preparation. As far as be concerned, supercritical fluid extraction (SFE) can overcome the deficiency of conventional methods, for instance the environmental pollution, difficulty in post-treatment and extraction of thermosensitive materials. In the field of chemical reaction, SCF exhibits many advantages such as avoiding use of harmful organic solvent, elevating the speed and selectivity of reaction, and adjusting the conversion of reactant and selectivity of product through changing pressure and temperature. Finally, the products with special properties will be obtained by use of the new techenique in material preparation. |
