Supercritical carbon dioxide has a special dissolution effect on certain special natural products. Supercritical carbon dioxide solubility is affected by pressure and temperature. Therefore, by adjusting the pressure and temperature, the solvency of the supercritical carbon dioxide can be adjusted to achieve the expectation.
Precautions for supercritical carbon dioxide extraction in terms of pressure
The extraction pressure is one of the most important parameters of SFE (supercritical fluid extraction). When the extraction temperature is constant, the pressure increases, the fluid density increases, the solvent strength increases, and the solubility of the solvent increases. The extraction pressure is quite different for different substances.
