General information on NO2 / Nitrogen dioxide

Nitrogen dioxide (NO2) is a reddish-brown, toxic, pungent chlorine-like smelling gas. The gas belongs to the group of nitrogen oxides and can be easily liquefied to N2O4 (dinitrogen tetraoxide) by increasing the pressure or cooling with dimerization. Nitrogen dioxide is used for the production of nitric acid. In trace amounts, nitrogen dioxide is formed from oxygen and nitrogen as the two main components of the atmosphere, both in natural processes such as lightning strikes and in technical combustion processes, e.g. in internal combustion engines.
