Description. Oxides of nitrogen are a mixture of gases that are composed of nitrogen and oxygen. Two of the most toxicologically significant compounds are nitric oxide (NO) and nitrogen dioxide (NO 2).Other gases belonging to this group are nitrogen monoxide (or nitrous oxide, N 2 O), and nitrogen pentoxide (NO 5).. Nitrogen dioxide is produced for the manufacture of nitric acid.

The Ostwald process is a chemical process that in two stages, converts ammonia to nitric acid (also known as HNO3). In the process for step 1, ammonia is oxidized to form nitric oxide and also nitrogen dioxide. Then in step 2, the nitrogen dioxide that was formed is absorbed in water. This in-turn forms nitric acid

Jul 22, 2016The influence of concentration of reactants (HNO 3 and TO) and reaction temperature on the rate of synthesis of NTO from TO in nitric acid solution was investigated by using an experimental kinetics model. An exponential kinetic equation was established by nitration of TO in 60.4–76.2 % HNO 3.Experimental data of the nitration of TO with 60.0–96.7 % HNO 3 were used to verify this model.
