Oxygen under high pressure

CO is bound to hemoglobin and does not allow it to carry oxygen. Oxygen under high pressure in the hyperbaric chamber is dissolved in the plasma and is carried to the tissues without the aid of hemoglobin. 

Similarly, indecisive results are obtained by the spectroscopic study of the luminous zone. A continuous band of colour is observed, and this would result whether the luminous particles were solids or dense hydrocarbon vapours. As is mentioned later (see p. 84), even the flame of hydrogen burning m oxygen under high pressures yields a continuous spectrum, and in this case the possibility of solid particles being present is entirely ruled out.

Under high pressures and temperatures, iodine reacts with oxygen to form iodine pentoxide [12029-98-0] (44). The reaction of iodine with carbon monoxide under acidic conditions is catalyzed by palladium salts (45). Phosphorous vapor and iodine react to form phosphoms trHodide [13455-01 -17, PI (46). 

COz is a nonflammable gas, therefore it does not present a tire or explosion hazard. The gas is generally considered toxic but will displace oxygen in the air, since it is 1.5 times heavier that air it wall settle and air supplies will be pushed out of the area. The CO2 gas is considered an asphyxiation hazard to personnel for this reason. Since the gas is odorless and colorless it cannot be easily detected by human observation in normal environments. Fire protection CO2 gas is normally stored under high pressure as a liquid and expands 350 times its liquid volume upon release. 

Instead of burning coal directly, coal gasification reacts coal with steam and carefully controlled amounts of air or oxygen under high temperatures and pressures. 

Methane hydrates form when methane molecules become trapped within an ice lattice as water freezes. They can form in very cold conditions or under high-pressure conditions. Both of these conditions are met in deep oceans and in permafrost. In Canada, hydrates have already been found in large quantities in the Canadian Arctic. Methane hydrate has a number of remarkable properties. For example, when brought into an oxygen atmosphere, the methane fumes can be ignited, making it appear that the ice is burning ... 

SrLaCu04 has been prepared (102) under high-pressure oxygen and the product has been found to contain the Cu3+ ion in a distorted octahedral environment, the Cu-O bond distances in the compound are 4 1.88 and 2 2.23 A. 

In this context, it is noteworthy that Over and co-workers (46,164-167) found the same types of Mars-van Krevelen mechanism for CO oxidation for ruthenium. Although the active surface was not characterized directly under high-pressure conditions in these investigations, it was found for the ruthenium(0 0 01) surface, which forms a RuO2(l 1 0) thin film in an oxygen-rich environment, that the activity of ruthenium as an oxidation catalyst is in fact primarily related to the RUO2 phase.
