sodium nitrite usage and synthesis

chemical properties	white to off-white powder
usage	sodium nitrite is a myeloperoxidase inhibitor with ic50 of 1.3 μm
general description	a yellowish white crystalline solid. noncombustible but will accelerate the burning of combustible material. if large quantities are involved in a fire or if the combustible material is finely divided, an explosion may result. if contaminated by ammonium compounds, spontaneous decomposition can occur and the resulting heat may ignite surrounding combustible material. prolonged exposure heat may result in an explosion. toxic oxides of nitrogen are produced in fires involving sodium nitrite. used as a food preservative, and to make other chemicals.
air & water reactions	soluble in water.
reactivity profile	sodium nitrite is an oxidizing agent. mixtures with phosphorus, tin(ii) chloride or other reducing agents may react explosively [bretherick 1979 p. 108-109]. if contaminated by ammonium compounds, spontaneous decomposition can occur and resulting heat may ignite surrounding combustible material. reacts with acids to form toxic nitrogen dioxide gas. mixing with liquid ammonia forms dipotassium nitrite, which is very reactive and easily explosive [mellor 2, supp. 3:1566 1963]. melting together wilh an ammonium salt leads to a violent explosion [von schwartz 1918 p. 299]. a mixture with potassium cyanide may cause an explosion. noncombustible but accelerates the burning of all combustible material. if large quantities are involved in fire or if the combustible material is finely divided, an explosion may result. when a little ammonium sulfate is added to fused potassium nitrite, a vigorous reaction occurs attended by flame [mellor 2:702. 1946-47].
health hazard	ingestion (or inhalation of excessive amounts of dust) causes rapid drop in blood pressure, persistent and throbbing headache, vertigo, palpitations, and visual disturbances; skin becomes flushed and sweaty, later cold and cyanotic; other symptoms include nausea, vomiting, diarrhea (sometimes), fainting, methemoglobinemia. contact with eyes causes irritation.
