Abstract. Water behaves as an ,acidic, and ,alkaline, precursor for ,acidic, or basic reactions, since the formation of both H 3 O + and OH – ions takes place in accordance with the self-dissociation of water at near-critical and above supercritical (T c = 374 °C, P c = 22.1 MPa) conditions. Therefore, supercritical water is considered both as a solvent for organic materials and as a reactant at ...
