Applicazioni

Nitromethane is used as a stabilizer of halogenated organic solvents, rocket and racing fuel and a chemical intermediate. It is also used as a solvent for cyanoacrylate adhesives, polymers and waxes. It serves as a Michael donor, adding to alfa,beta-unsaturated carbonyl compounds through 1,4-addition in the Michael reaction. It acts as a solvent used for extractions, reaction medium and as a cleaning solvent. Further, it is used in the manufacture of pharmaceuticals, explosives, fibers and coatings.

Note

Incompatible with amines, strong acids, strong bases, strong oxidizing agents, strong reducing agents and copper

For conditions for the Henry (nitro-aldol) condensation of nitroalkanes with carbonyl compounds, see 1-Nitropropane, A11975 . In the Tiffeneau-Demjanov ring expansion of ketones, the nitro aldol is reduced to the ß-hydroxyamine before diazotization; see, e.g. (cyclohexanone to cycloheptanone): Org. Synth. Coll., 4, 221 (1963); review: Org. React., 11, 157 (1960).

For a review of the use of nitro compounds as alkyl anion synthons, including methods for removing the nitro group from the resulting carbon skeletons, see: Synthesis, 833 (1988).
