Dinitromethane is an organic compound with the chemical formula CH2(NO2)2.[1] Purified dinitromethane is a colorless liquid with a weak pleasant odor. It is relatively stable at room temperature and can be safely stored for months at 0 °C.[2]

Synthesis

The potassium salt of dinitromethanide, KCH(NO2)2, was first prepared by Villiers in 1884 by reduction of bromodinitromethane.[3] Hydrogen fluoride and the potassium salt of dinitromethane react in diethyl ether to form dinitromethane.[2] Free dinitromethane was previously understood to be a pale, yellow oil that decomposed rapidly at ambient temperatures.[4]

Dinitromethane should not be confused with methylene dinitrate (CH2(ONO2)2), which is produced as a byproduct in the production of the explosive RDX.[5]

Safety

The transportation of dinitromethane is forbidden by the U.S. Department of Transportation.[6]
