OPA oxidation rates in supercritical water
Journal of Hazardous Materials, 2005Supercritical water oxidation can effectively destroy a large variety of high-risk wastes resulting from munitions demilitarization and complex industrial chemical. An important design consideration in the development of supercritical water oxidation is the information on the oxidation rate.

Thermal Lensing in a Supercritical Water Medium
The Journal of Physical Chemistry A, 2006A pulsed, two-beam, thermal lensing experiment was performed to determine the concentration of aqueous solutes above the critical point of water. Despite a very significant mirage effect due to thermal gradients in the cell and absorption by water itself, the thermal lensing signal strength for aqueous benzoic acid in supercritical water was found to ...

Hydrogen Bonded Networks in Supercritical Water
The Journal of Physical Chemistry B, 2014In this study, the structure of supercritical water (SCW) is investigated by Raman spectroscopy and molecular dynamics simulations. It was found that the hydrogen bonding in water is closely related to temperature and pressure (or water density). According to the Raman spectroscopic study of SCW, the existence of tetrahedral hydrogen bonds in SCW is ...

Hydrothermal synthesis of particles is usually carried out at subcritical conditions in batch reactors. In supercritical region, reaction rate increases dramatically due to low dielectric constant (ɛ) of SCW. Therefore, fine particles (e.g., metal oxides) are rapidly synthesized (e.g., 0.4 s∼2 min) in a continuous SCW process.

Chemistry in Supercritical Water.
Angewandte Chemie (International ed. in English)Water is a special liquid-and not only under "normal" conditions. Water in the supercritical state (shaded area in the phase diagram) is distinguished by special properties which are wholly at variance with those of normal water. So far these have usually been exploited for the purification of waste water, for example for the complete oxidation of ...
