Nitroethane is an organic compound having the chemical formula C 2 H 5 NO 2. Similar in many regards to nitromethane , nitroethane is an oily liquid at standard temperature and pressure. Pure nitroethane is colorless and has a fruity odor. This exothermic reaction produces four industrially significant nitroalkanes: nitromethane , nitroethane, 1-nitropropane , and 2-nitropropane. These alkoxy radicals are susceptible to C—C fragmentation reactions, which explains the formation of a mixture of products. Alternatively, nitroethane can be produced by the Victor Meyer reaction of haloethanes such as chloroethane , bromoethane , or iodoethane with silver nitrite in diethyl ether or THF. The Kornblum modification of this reaction uses sodium nitrite in either a dimethyl sulfoxide or dimethylformamide solvent. Via condensations like the Henry reaction , nitroethane converts to several compounds of commercial interest. Condensation with 3,4-dimethoxybenzaldehyde affords the precursor to the antihypertensive drug methyldopa ; condensation with unsubstituted benzaldehyde yields phenylnitropropene. Nitroethane condenses with two equivalents of formaldehyde to give, after hydrogenation , 2-aminomethyl-1,3-propanediol, which in turn condenses with oleic acid to give an oxazoline, which protonates to give a cationic surfactant. Like some other nitrated organic compounds, nitroethane is also used as a fuel additive and a precursor to Rocket propellants. Nitroethane is a useful solvent for polymers such as polystyrene and is particularly useful for dissolving cyanoacrylate adhesives. In cosmetics applications, it has been used as a component in artificial nail remover and in overhead ceiling sealant sprays. Nitroethane was previously used successfully as a chemical feedstock precursor ingredients in laboratories for the synthesis of multitudes of substances and consumer goods, for e. Nitroethane is suspected to cause genetic damage and be harmful to the nervous system. Typical STEL is ppm. Skin contact causes dermatitis in humans. In animal studies, nitroethane exposure was observed to cause lacrimation , dyspnea , pulmonary rales, edema , liver and kidney injury, and narcosis. From Wikipedia, the free encyclopedia.
