Air and Water Reactions:Decomposes rapidly at room temperature or when dissolved in hot water by internal oxidation-reduction. Reacts with water or steam to produce heat and corrosive liquids.
Reactive Group:Bases, Strong
Reactivity Alerts:Explosive
Reactivity Profile:HYDROXYLAMINE is a white solid, thermally unstable, decomposes rapidly at room temperature or when dissolved in hot water by internal oxidation-reduction. It should be stored below 10° C [Bailar, 1973, vol. 2, p. 272]. Explosive reaction with strong oxidizers (chromium trioxide, potassium dichromate) or powdered zinc upon heat. Reaction with zinc or calcium produces explosive bishydroxylamides. It ignites on contact with cupric sulfate, alkali metals (sodium, potassium), oxidants (e.g., barium oxide, barium peroxide, lead dioxide, potassium permanganate, chlorine), phosphorus trichloride and pentachloride. It reacts vigorously with hypochlorites, pyridine, carbonyls [Sax, 9th ed., 1996, p. 1875]. On contact with organic materials in thin layer (e.g., crystals on filter paper), it may ignite spontaneously in air. It explodes when heated above 70° C [Brauer, 1963, vol. 1, p. 502]. During a distillation process, an explosion occurred. Potassium hydroxide is thought to be involved in the explosion. Employees in the plant complained of chest pains and suffered chemical burns. Five people were killed by the explosion.
Autoignition Temperature:265 °F (USCG, 1999)
