pressurized hot-water extraction

synonyms: subcritical water extraction, superheated water extraction
https://doi.org/10.1351/goldbook.10226
Extraction by water below its critical point (\(\pu{374.15^{\circ}C}\) and \(\pu{22.064 MPa}\)).
Notes:
  1. The solvation properties of water become closer to organic solvents at elevated temperatures.
  2. Instrument requirements are similar to pressurized-liquid extraction.
