Preparation of Nitromethane: this chemical is produced industrially by treating propane with nitric acid at 350–450 °C (622–842 °F). In addition, it can be prepared in other methods that are of instructional value. The reaction of sodium chloroacetate with sodium nitrite in aqueous solution produces this compound:

ClCH₂COONa + NaNO₂ + H₂O → CH₃NO₂ + NaCl + NaHCO₃

Uses of Nitromethane: The principal use of nitromethane is as a stabilizer for chlorinated solvents, which are used in dry cleaning, semiconductor processing, and degreasing. It is also used most effectively as a solvent or dissolving agent for acrylate monomers, such as cyanoacrylates. In organic synthesis nitromethane is employed as a one carbon building block. In more specialized organic synthesis, nitromethane serves as a Michael donor, adding to α,β-unsaturated carbonyl compounds via 1,4-addition in the Michael reaction. In a minor application, nitromethane is used as a fuel in racing, particularly drag racing, as well as for rockets and model airplanes and commonly referred to in this context as "nitro". Nitromethane can also be used as a monopropellant, i.e., a fuel that burns without added oxygen. The following equation describes this process:

2 CH₃NO₂ → 2 CO + 2 H₂O + H₂ + N₂

When you are using this chemical, please be cautious about it. This chemical is harmful if swallowed. In addition, it is highly flammable and irritant. If heating may cause an explosion. In case of fire and/or explosion do not breathe fumes.
