What does nitration mean?
Nitration is a chemical reaction in which a nitro group, –NO₂, is introduced into a compound. It is most commonly associated with organic chemistry, where nitric acid or a related reagent reacts with an aromatic compound, often with sulfuric acid serving as a catalyst or acidifying agent. The process is technically important because nitrated compounds are widely used as intermediates in the manufacture of dyes, pharmaceuticals, agricultural chemicals, and energetic materials. In organic reactions, nitration is generally a substitution process: one hydrogen atom is replaced by a nitro group. Because these reactions can be vigorous, exothermic, and potentially hazardous, industrial nitration requires controlled temperature, acid concentration, mixing, and safety procedures. The term is specialized and is rarely used outside chemistry and closely related technical fields.
nounThe chemical process of introducing a nitro group (–NO₂) into a compound, usually by reaction with nitric acid or a related nitrating agent. The term most often refers to this substitution reaction in organic chemistry.
- The chemical introduction of a nitro group into an organic compound.
"The nitration of benzene produces nitrobenzene under carefully controlled conditions."
"Careful control of temperature and concentration is essential during the nitration of aromatic compounds."
"The industrial nitration process uses nitric acid and sulfuric acid to produce an important intermediate."
Plural is used when referring to multiple nitration reactions or processes.
"Researchers compared several nitrations performed under different temperature conditions."
Nitration is the key step in making many useful compounds, including explosives, dyes, medicines, and fertilizers.

Where does nitration come from?
The word derives from nitrate, which in turn comes through the Latin-language chemical vocabulary associated with nitre, another name for sodium nitrate. The suffix -ation forms a noun denoting a process or action, so nitration literally means “the formation or introduction of nitrate or nitro groups.” The terminology developed as organic chemists systematized reactions involving nitrogen-containing compounds.

How nitration is actually used
In chemistry, nitration normally means the substitution of a hydrogen atom by a nitro group; it should not be confused with the nontechnical use of nitrate as a fertilizer or food additive.
