Technical characteristics of supercritical CO2 extraction

Extraction can be carried out at close to room temperature (35-40 ℃) and under CO2 gas cover, preventing the oxidation and dissipation of heat-sensitive substances. Therefore, all the components of medicinal plants are maintained in the extract, and the substances with high boiling point, low volatility and easy pyrolysis can be extracted below their boiling point temperature;

What kinds of supercritical extraction devices are divided?

Supercritical extraction devices can be divided into two types, one is the research and analysis type, which is mainly used for the analysis of small amounts of substances or to provide data for production. The second is the preparation of production, mainly used in batch or mass production.

Prospect and Prospect of Supercritical Extraction Separation

Substances exist in the form of gas, liquid and solid, and can undergo phase transitions at different pressures and temperatures. When the temperature is higher than a certain value, any large pressure can not make the pure substance from the gas phase to the liquid phase, the temperature at this time is called the critical temperature Tc; and at the critical temperature, the low pressure at which the gas can be liquefied is called the critical pressure Pc.
