Oxides high-temperature oxygen

At high temperatures oxygen reacts with the nitrogen in the air forming small amounts of nitrogen oxide (p. 210). Sulphur burns with a blue flame when heated in air to form sulphur dioxide SO2, and a little sulphur trioxide SO3. Selenium and tellurium also burn with a blue flame when heated in air, but form only their dioxides, Se02 and Te02.

The forces which hold A to the free surface of a continuous mass of M may be of any kind— van der Waals forces, whether of the London type or of the dipolar type, interionic forces, or covalencies. The adsorption of gases by charcoal at low temperatures depends upon van der Waals forces. At high temperatures oxygen is held by covalencies. Oxygen and hydrogen may, according to circumstances, be taken up by metals as molecular layers or as surface films of oxide or hydride.

This commercial process requires pressurization and a relatively high temperature. Oxygen is the oxidizing agent, and acetic acid (CH3COOH) is the solvent. An alternative route employs supercritical water as the solvent and hydrogen peroxide as the oxidant. This alternative process has several potential advantages, most particularly the elimination of acetic acid as solvent.
