hydrogen cyanide usage and synthesis

general description	hydrocyanic acid solution is water containing up to 5% dissolved hydrocyanic acid with the faint odor of almonds. hydrogen cyanide is toxic by inhalation and skin absorption. prolonged exposure to low concentrations or short term exposure to high concentrations may result in adverse health effects. its vapors are just barely lighter than air.
reactivity profile	this particular record contains hydrogen cyanide dissolved in water. hydrogen cyanide is a very volatile liquid or colorless gas smelling of bitter almonds, b.p. 26° c. a deadly human poison by all routes. the gas (hydrogen cyanide) forms explosive mixtures with air, hydrogen cyanide reacts violently with acetaldehyde. hydrogen cyanide is a severe explosion hazard when heated or exposed to oxidizers. hydrogen cyanide may polymerize explosively at elevated temperature (50-60° c) or in the presence of traces of alkali [wohler, l. et al., chem. ztg., 1926, 50, p. 761, 781]. in the absence of a stabilizer (e.g., phosphoric acid) hydrogen cyanide may undergo explosively rapid spontaneous (autocatalytic) polymerization leading to a fire. the reaction is autocatalytic because of ammonia formation. the anhydrous acid should be stabilized by the addition of acid. [bond, j., loss prev. bull., 1991, 101, p.3]. during the preparation of imidoester hydrochlorides, hydrogen chloride was rapidly passed over alcoholic hydrogen cyanide. an explosion ensued, even with cooling of the process, [j. org. chem., 1955, 20, 1573].
health hazard	toxic; inhalation, ingestion or skin contact with material may cause severe injury or death. contact with molten substance may cause severe burns to skin and eyes. avoid any skin contact. effects of contact or inhalation may be delayed. fire may produce irritating, corrosive and/or toxic gases. runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
fire hazard	non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). contact with metals may evolve flammable hydrogen gas. containers may explode when heated.
