Classification Characteristics And Applications Of Supercritical Carbon Dioxide Fluid Extraction

Supercritical fluid refers to a fluid whose temperature and pressure are above its critical temperature (Tc) and critical pressure (pc), between gas and liquid. Stable pure substances can all have a supercritical state (stable means that their chemical properties are stable and will not decompose into pure substances when reaching the critical temperature), and they all have their fixed critical points: critical temperature and critical pressure.
