potassium hydroxide usage and synthesis

chemical properties	white crystals, flakes, sticks or pellets
general description	a white solid. corrosive to metals and tissue. used in soap manufacture, bleach, as an electrolyte in alkaline batteries, and as a food additive.
air & water reactions	hydrolysis generates enough heat to ignite adjacent combustible material [haz. chem. data 1966]. dissolves in water (with liberation of heat, may steam and spatter. solution is basic (alkaline). deliquescent
reactivity profile	potassium hydroxide absorbs moisture readily forming caustic solution that attacks aluminum and zinc. a piece of potassium hydroxide causes liquid chlorine dioxide to explode [mellor 2:289. 1946-47]. 1,2-dichloroethylene and potassium hydroxide forms chloroacetylene, which is explosive and spontaneously flammable in air. potassium hydroxide is highly toxic [rutledge 1968. p. 134]. a reaction between n-nitrosomethylurea and potassium hydroxide in n-butyl ether resulted in an explosion due to the formation of diazomethane [schwab 1972]. potassium persulfate and a little potassium hydroxide and water ignited a polythene (polyethylene) liner of a container by release of heat and oxygen [mca case history 1155. 1955]. using potassium hydroxide to dry impure tetrahydrofuran, which contains peroxides, may be hazardous. explosions have occurred in the past. sodium hydroxide behaves in a similar way as potassium hydroxide [nsc newsletter chem. soc. 1967]. a strong base. forms caustic solution in water. [merck 11th ed. 1989].
health hazard	causes severe burns of eyes, skin, and mucous membranes.
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.
