hydroxylamine usage and synthesis
chemical properties slightly yellow liquid
general description odorless white crystalline solid. sinks and mixes with water.
air & 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.
reactivity profile hydroxylamine is a white solid, thermally unstable, decomposes rapidly at room temperature or when dissolved in hot water by internal oxidation-reduction. hydroxylamine 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. hydroxylamine 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. hydroxylamine 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), hydroxylamine may ignite spontaneously in air. hydroxylamine 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.
health hazard inhalation: moderately toxic by inhalation and oral routes with the following symptoms possible: headache, vertigo, tinnitus, dyspnea, nausea and vomiting, cyanosis, proteinuria and hematuria, jaundice, restlessness, and convulsion. methemoglobinemia has been reported. eyes: corrosive - highly irritating. skin: irritating or corrosive to skin. ingestion: moderately toxic by inhalation and oral routes with the following symptoms possible; headache, vertigo, tinnitus, dyspnea, nausea and vomiting, cyanosis, proteinuria and hematuria, jaundice, restlessness, and convulsion. methemoglobinemia has been reported.
