Nitrogen tetroxide

CAS RN: 10544-72-6

Reactivities / Incompatibilities

Stong oxidizers that enhance the combustion of easily oxidized materials, reducing agents, combustibles, organics. /Nitrogen oxides/
The oxides of nitrogen react with a broad range of materials, and decomposition may occur under certain conditions. /Nitrogen oxides/
A violent explosion ocurred during the ready interaction to produce alkyl nitrates.
Liquid ammonia reacts explosively with the solid tetraoxide at -80 deg C, while aqueous ammonia reacts vigorously with the gas at ambient temperature.
In contact with the gas at 200 deg C the barium oxide suddenly reacts, reaches red heat and melts.
Mixtures of the tetraoxide with dichloromethane, chloroform, carbon tetrachloride, 1,2-dichloroethane, trichloroethylene and tetrachloroethylene are explosive when subjected to shock of 25 g TNT equivalent or less. Mixtures with trichloroethylene react violently on heating to 150 deg C
Dinitrogen tetraoxde reacts explosively between -32 deg C and -90 deg C with propene, 1-butene, isobutene, 1,3-butadiene, cyclopentadiene and 1-hexene, but 6 other unsaturated failed to react.
Warm or molten white phosphorus burns vigorously in nitrogen oxide, dinitrogen tetraoxide or dinitrogen pentaoxide. White phosphorus ignites after some delay in contact with the vapor of sulfur trioxide, but immediately in contact with the liquid if a large portion is used.
Interaction with the oxide in carbon tetrachloride is vigorous, producing sparks.
A wide variety of solids, liquids and gases will initiate the violent and often explosive decomposition of nitrogen trichloride. These include conc ammonia, arsenic, dinitrogen tetroxide (above -40 deg C, with more than 25% solutions of trichloride in chloroform), hydrogen sulfide, hydrogen trisulfide, nitrogen oxide, organic matter (including grease from the fingers), ozone, phosphine, phosphorus (solid, or in carbon disulfide solution), potassium cyanide (solid, or aqueous solution), potassium hydroxide solution or selenium.
