Nitrogen oxide, mono

In explosives, diphenylamine stabilizes cellulose nitrate by reacting with nitrogen oxides (see Explosives and propellants). The products formed include /V-nitrosodiphenylamine and mono andpolynitro derivatives. 

Reduction products of nitric acid, such as nitrogen and nitrogen oxides can also be formed as the result of oxidation processes. Niederer [148] found that N2 and NO were not formed in the nitration of nitro- to dinitrotoluene, while they were present in the nitration products of di- to tri-nitrotoluene. In addition to nitrogen and nitrogen oxide, carbon mono- and dioxide were formed in the last stage of nitration. Their amount and the CO to C02 ratio increased with temperature. 

The products such as the mono- and di-hydroxy derivatives of the hydrocarbons, which are essential to the theory, have not been found experimentally except under special conditions where other factors are involved. An aldehyde and water have usually been the first products of oxidation to be observed.8 The explanation offered by Bone and Stockings 20 for the non-appearance of mono-hydroxy products in the experiments is that the primary alcohols undergo such rapid oxidation or decomposition that their presence in the product could not be expected. This is not in accord with the results of other workers who have found that in the case of paraffins higher than ethane the alcohols are more difficult to oxidize than the corresponding normal paraffins or normal aldehydes.4 It lias also been possible under certain circumstances, such as oxidation in the presence of nitrogen oxides, ozone, etc., to actually obtain the alcohol. It is difficult to see why, if the alcohol is so much more easily oxidized than the hydrocarbon, it would not be destroyed in these cases as well as in the process of direct oxidation where aldehydes but not alcohol have been found.

Nitrogen forms no less than eight binary oxides that are sufficiently stable have their molecular structures determined in the gas phase, viz. the three mono-nitrogen oxides NO t, k = I, 2 or 3, and the five di-nitrogen oxides N20, k = 1-5. 

When the vowels 0 and o or a and o appear together, the first vowel is omitted, as in carbon monoxide. In the name of a molecular compound, the prefix mono is usually omitted, as in NO, nitrogen oxide. Traditionally, however, CO is named carbon monoxide. Table 6.12 lists the formulas, names, and commercial uses of some common molecular compounds.
