Description
Nitric Acid Product Overview
Nitric acid (HNO3) is a clear, colorless to yellowish liquid. Commercial grades usually contain 53–68% acid; 68% is the azeotropic concentration, and fuming grades exceed 86%. The yellow color comes from dissolved nitrogen dioxide formed by decomposition in light.
Most production goes into fertilizers such as ammonium nitrate and calcium ammonium nitrate. The chemical industry uses it for nitration, for example to make nitrobenzene for aniline and the intermediates of polyurethane raw materials, and to oxidize cyclohexanone to adipic acid for nylon. It also serves as the raw material for nitrates such as Potassium Nitrate.
In metal treatment, nitric acid pickles and passivates stainless steel and etches metals in electronics. Precious metal refiners combine it with hydrochloric acid in aqua regia. For other mineral acids, see Sulfuric acid and Phosphoric acid. In the EU, nitric acid above 3% is a restricted explosives precursor that may not be sold to the general public.
