dinitración
Dinitration is a chemical reaction that involves the introduction of two nitro groups (-NO2) onto a molecule. Typically, this process occurs in organic chemistry, often on aromatic rings. The nitration of benzene, for instance, can proceed to dinitration under more vigorous conditions than mononitration. This usually requires stronger nitrating agents, such as a mixture of concentrated nitric acid and sulfuric acid, and often elevated temperatures.
The regioselectivity of dinitration, meaning the positions at which the two nitro groups attach to the ring,
Dinitration is an important synthetic step in the production of various chemicals. For example, dinitrotoluene is
