ethylene oxide usage and synthesis

chemical properties	colourless gas
general description	a clear colorless gas with an ethereal odor. flash point below 0°f. may polymerize exothermically if heated or contaminated. if the polymerization takes place inside a container, the container may rupture violently. vapors may burn inside a container. vapors irritate the eyes, skin, and respiratory system. prolonged skin contact may result in delayed burns. less dense than water. vapors heavier than air. vapors very toxic. under prolonged exposure to fire or heat the containers may rupture violently and rocket. used to make other chemicals, as a fumigant and industrial sterilant (aar, 1999).
air & water reactions	highly flammable. flammable over a wide vapor-air concentration range. must be diluted on the order of 24 to 1 with water to lose flammability. soluble in water.
reactivity profile	colorless gas at room temperature (b.p. 11°c), confirmed carcinogen. highly flammable, severe explosion hazard when exposed to flame. the autoignition temperature may be as low as 140° c in presence of rust. rapid compression of the vapor with air causes explosion. ethylene oxide vapor may be initiated into explosive decomposition in absence of air [hess, l. g., et al., ind. eng. chem., 1950, 42, p. 1251]. metal fittings containing magnesium, copper or silver should be avoided, since traces of acetylene in ethylene oxide may produce metal acetylides capable of detonating the vapor [mca sd-38, 1971]. violent polymerization occurs on contact with strong bases (alkali hydroxides, ammonia) or acids, amines, metallic potassium, oxides (aluminum oxide, iron oxide, rust), covalent halides (aluminum chloride, ferric chloride, tin(iv) chloride) [gupta, a. k., j. soc. chem. ind., 1949, 68, p. 179]. violent reaction with m-nitroaniline, magnesium perchlorate, mercaptans, thiols, triethylamine [bretherick, 5th ed., 1995, p. 316]. ethylene oxide and so2 can react violently in pyridine solution with pressurization if ethylene oxide is in excess (nolan, 1983, case history 51).
health hazard	ethylene oxide can cause death. lowest inhalation concentration causing toxic effects is 12500 ppm/10 seconds. it is a strong skin irritant. neurological disorders and even death have been reported.
fire hazard	severe explosion hazard when exposed to heat or flame. irritating vapors are generated when heated. vapor is heavier than air and may travel considerable distance to a source of ignition and flash back. vapor forms explosive mixtures with air over a wide range. liquid is not detonable but the vapor may be readily initiated into explosive decomposition. avoid metal fittings containing copper, silver, mercury or magnesium; ammonia, oxidizing agents; acids, organic bases; amines; certain salts; alcohols; mercaptans, ferric chloride; magnesium perchlorate; m-nitroaniline; trimethylamine, potassium, tin chlorides; alkanethiols; bromoethane; aluminum chloride; aluminum oxide; iron chlorides; and iron oxides. avoid air, heat, acids and bases, metal or metal chloride catalysts. hazardous polymerization may occur. avoid acids; covalent halides such as chlorides of aluminum, iron (iii), tin (iv); basic materials like alkali hydrides, ammonia, amines, and potassium; catalytically active solids such as aluminum or iron oxides or rust, chlorides of boron, aluminum, tin, and iron; some carbonates; and metals such as copper and copper alloys
