Preparation: this chemical is produced industrially by treating propane with nitric acid at 350–450 °C. This exothermic reaction produces four industrially significant nitroalkanes: nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane. The reaction involves free radicals, such as CH3CH2CH2O, which arise via homolysis of the corresponding nitrite ester. These alkoxy radicals are susceptible to C-C fragmentation reactions, which explains the formation of a mixture of products.
Uses of Nitroethane: it 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 phenyl-2-nitropropene. Nitroethane condenses with two equivalents of formaldehyde to give, after hydrogenation, 2-amino-2-methyl-1,3-propanediol, which in turn condenses with oleic acid to give an oxazoline, which protonates to give a cationic surfactant. Nitroethane is also used as a fuel additive and a precursor to explosives. Nitroethane is a useful solvent for polymers such as polystyrene and is particularly useful for dissolving cyanoacrylate adhesives.[citation needed] In niche applications, it has been used as a component in artificial nail remover and in overhead ceiling sealant sprays.
When you are using this chemical, please be cautious about it as the following:
It is flammable and harmful by inhalation and if swallowed. Besides, this chemical may cause cancer. When you are using it, do not breathe gas/fumes/vapour/spray (appropriate wording to be specified by the manufacturer) and avoid contact with eyes. In case of fire and/or explosion do not breathe fumes.
