Applications of Nitric acid:

Nitric acid is an important chemical raw material, mainly used in the manufacture of ammonium nitrate, calcium ammonium nitrate, nitrate phosphate fertilizer, nitrogen phosphate potassium and other complex fertilizers. As an essential raw material for nitrate nitrogen fertilizer (such as ammonium nitrate, potassium nitrate, etc.), aqua regia, nitroglycerin, nitrocellulose, nitrobenzene, picric acid and nitrate ester, it is also used to make nitro-containing explosives.

Organic industry

Used in the manufacture of tetranitromethane, nitrohexane, L-nitropropane, 2, 4-dinitrophenoxyethanol and other nitrocompounds.

Dye industry

Used for the synthesis of dye intermediates such as p-nitroanisole, 4,4 '-dinitrodiphenyl ether, p-nitrophenol and 2, 5-dichloronitrobenzene.

Coating industry

Used in the manufacture of nitrocellulose varnish and nitrocellulose enamel.

Pharmaceutical industry

Used to make nitroacetophenone.

Water treatment

Nitric acid can be used as a cleaning agent for carbon steel and stainless steel equipment, and is used in the REDOX treatment process of sewage and waste water. In the process of biological treatment of sewage, it can be used as a nitrogen source in microbial nutrients.

Other role

Nitric acid is used as an oxidizing agent to oxidize alcohols, anilines and other chemicals. And has been used as propellant for rockets. Nitric acid is also the raw material for nitrates such as calcium, copper, silver, cobalt and strontium. Nitric acid is also used to refine metals (i.e. to oxidize impure metals to nitrates, remove impurities and then reduce them).

Nitric acid has a corrosive effect on most metals. High concentration nitric acid has a passivating effect on metals. It has good solubility to α-Fe2O3 and magnetic Fe3O4.

Nitric acid is used as etching agent and strong acid cleaning etch agent, can be used with glacial acetic acid, hydrogen peroxide, etc.

Nitric acid is used as an analytical agent, e.g. as a solvent, oxidant. It is also used in organic synthesis to produce various nitro compounds.
