Oxygen reaction with nitrogen

Reactions with Oxygen and Nitrogen Reactions with Oxygen... 

There is a reaction between beryllium and nitrogen that starts at about 750°C and is appreciable at 850°C, beryllium nitride being formed". The reaction with oxygen is less sluggish and at 900°C in oxygen oxidation proceeds at about twice the rate of nitride formation. Thus when beryllium is heated in air, beryllium nitride forms only a small proportion of the total scale —about 0-75% after 1 h at 1 000°C. 

Sometimes, knowing only the magnitude of the equilibrium constant, it is possible to decide on the feasibility of a reaction. Consider, for example, a possible method for fixing atmospheric nitrogen—converting it to a compound—by reaction with oxygen ...

At least since the mid-19th century, it has never been claimed that molecular nitrogen is completely unreactive with organic reagents. It was, however, known that many reactions that cannot be carried out in air because of reactions with oxygen, can be performed in a so-called inert atmosphere consisting of either a noble gas or — more cheaply — N2. This is common knowledge to the experimental chemist.

Clearly, the short half-life of nitric oxide is an important determinant for its biological function, but the chemical basis for this short half-life is still unknown. It cannot be due to the most commonly accepted mechanism reaction with oxygen to form nitrogen dioxide. 

Methyl benzoate, anisole, and diphenyl ether each give sandwich compounds with chromium vapor, although in rather low yield (32, 55, 110). Chromium appears to attack alkyl ethers and this deoxygenation probably competes with complexation with the aromatic oxygen compounds. No simple product has been isolated from chromium atoms and aniline, but bis(7V,7V-dimethylaniline)chromium has been prepared (32). The behavior of molybdenum and tungsten vapors closely resembles that of chromium in reactions with oxygen- and nitrogen-substituted arenes (113). 

LI Reactions of Nitrogen Oxides. Molecular nitrogen, N2, is the major component of air, and it is a very stable and chemically inert species. However, it can form various oxides by reaction with oxygen at high temperatures, such reactions being important in combustion processes. In the presence of atomic oxygen O an overall destruction of ozone takes place. 

The diaryl or aryl alkyl tellurides are dense yellow oils or crystalline solids, which are easier to handle than the dialkyl tellurides of similar molecular weight. Some of the diaryl derivatives are almost odorless solids. The same comments are valid for the diorganoditellurides 4, which are dark red oils (aliphatic derivatives) and dark red solids (aromatic derivatives). It is recommended that solutions of tellurides or ditellurides should not be kept in contact with air, since an amorphous white solid will form after some time. For some compounds, this reaction with oxygen is very fast. Aliphatic derivatives are more air sensitive than the aromatic ones. In view of this fact, it is recommended to bubble nitrogen into the solutions while a column or thin-layer chromatographic separation is performed. Evaporation of the solvent, however, minimizes the air oxidation. Pure liquids or solids can be handled in air with no need for special precautions, but prolonged exposure to air and to ambient light should be avoided. 

The carbide is difficult to keep pure because of its rapid reaction with oxygen or nitrogen in any form above RT and the rapid reaction with HjO or its vapor at all Ts. The CjHj resulting from this reaction may cause an explosion hazard. 

The reduction in the concentration of nitrogen is also brought about by reaction with oxygen for energy and for the requirement for synthesis. NBOD is actually in the form of NH3. Reacting with O2,...
