2-nitropropane is a nitro-derivative of the propane.

Occurrence and production

2-nitropropane is formed by the combustion of tobacco and other nitrate-rich organic material. One hand it can be prepared from nitric acid and an excess of propane in the vapor phase, wherein the ratio of the resulting nitro compounds depends on the temperature. On the other hand, it can be synthesized by reaction of dinitrogen tetroxide with propane in the presence of excess oxygen.


2-nitropropane is a clear oily liquid. Technical nitropropane may have a light yellow color. It is flammable, moderately volatile and forms explosive mixtures with air. 2- nitropropane is stable under normal conditions, but reacts with basic substances under deprotonation at the central carbon atom. The resulting aci -nitropropane anion may explode violently when heated or concentration of solutions. 2- nitropropane is slightly soluble in water, but miscible with many organic solvents. It is itself an excellent solvent for many organic compounds.


It is rarely used as a solvent. Furthermore, it is used as a fuel additive.


The main route of 2- nitropropane resorbed via respiratory tract. Acute to be reckoned with irritation of the eyes, mucous membranes and respiratory tract. Furthermore, disorders of the central nervous system and the gastrointestinal system, blood damage, and liver damage may occur. Symptoms of poisoning are headache, dizziness, staggering gait, vomiting and abdominal pain.

2- nitropropane is carcinogenic in animal experiments.

Chronic intake causes severe liver damage; a proven case led after 3 weeks for the death of a worker.
