Supercritical fluid extraction

{
  "id": "MLC-T-CHM-011597",
  "term": "Supercritical fluid extraction",
  "field": "Chemistry",
  "definition": "An extraction process that uses a supercritical fluid as the extraction solvent to separate one component from another. The substance is heated and pressurized above its critical point, where it exhibits properties of both a liquid and a gas, allowing it to diffuse through solids like a gas and dissolve materials like a liquid. Carbon dioxide is a widely used solvent for this technique because its critical point (31.1 °C and 73.8 bar) is easily accessible.",
