N-Nitrocarbamide Usage And Synthesis
General Description A colorless to white crystalline powder solid. Mildly sensitive to heat and shock. An extremely powerful explosive. Decomposes to emit toxic nitrogen oxide fumes. May explode under exposure to intense heat or fire. Primary hazard is blast of an instantaneous explosion, not flying projectiles or fragments.
Air & Water Reactions Hydrolysis occurs in water.
Reactivity Profile Explosive mercury or silver salts are rather sensitive to heat and impact, while the pure material is much more insensitive. Organonitrate compounds, such as N-Nitrocarbamide, range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. Nitroalkanes are milder oxidizing agents, but still react violently with reducing agents at higher temperature and pressures. Nitroalkanes react with inorganic bases to form explosive salts. The presence of metal oxides increases the thermal sensitivity of nitroalkanes.
Health Hazard Fire may produce irritating, corrosive and/or toxic gases.
Fire Hazard MAY EXPLODE AND THROW FRAGMENTS 1600 meters (1 MILE) OR MORE IF FIRE REACHES CARGO.
