nitrometanin

Nitromethane is the simplest organic nitro compound, with the chemical formula CH3NO2. It is a colorless, oily liquid that is the most viscous of the common nitroalkanes. Nitromethane is a polar solvent and is used in a variety of applications, including as a fuel additive, a solvent for resins and polymers, and as a precursor in the synthesis of other chemicals. It is also known for its use in racing fuels, particularly in drag racing, where it can provide a significant power boost.

Industrially, nitromethane is produced by the gas-phase nitration of propane. This process yields a mixture of nitroalkanes, from which nitromethane is separated by distillation. Its properties as a solvent stem from its polarity, allowing it to dissolve a range of organic and inorganic substances. Its high octane rating and energy density make it attractive as a fuel component. However, nitromethane is also a potentially hazardous substance. It is flammable and can be explosive under certain conditions, particularly when mixed with strong oxidizers or heated under confinement. Due to these properties, its handling and storage require specific safety precautions. It is also used in certain chemical reactions as a source of the nitromethyl group.
