What is the main structure of a mobile phone?

The mobile phone is to use the dissolution ability of the supercritical fluid is closely related to its density, by changing the pressure or temperature to make the density of the supercritical fluid change significantly, in the supercritical state, the supercritical fluid and the substance to be separated touched, so that it selectively extracts the polarity, boiling point and relative molecular mass in turn.
Supercritical fluid extraction
It is the world's advanced physical extraction technology, at a lower temperature, when the pressure of gas is continuously added, the gas will be converted into a liquid, when the pressure increases, the volume of the liquid increases, for a specific substance there is always a critical temperature (Tc) and critical pressure (Pc), higher than the critical temperature and critical pressure, the substance will not become liquid or gas, this is the critical point.

When extracting natural products by supercritical extraction method, CO2 is generally used as an extractant, the critical temperature and critical pressure are low, the operating conditions are mild, and the damage to the active ingredients is less, so it is especially suitable for the treatment of high boiling point heat-sensitive substances, such as flavors, fragrances, oils, vitamins, etc.; In the supercritical CO2 extraction, the extracted substances can be separated by falling pressure or increasing temperature, without repeated extraction operations, so the supercritical CO2 extraction process is simple, so supercritical CO2 extraction is particularly suitable for the extraction and purification of organisms, food, cosmetics and drugs.
