Knowra Ethylene oxide Ethylene oxide Ethylene oxide is a colorless, flammable, reactive gas used to manufacture chemicals and sterilize heat-sensitive medical equipment. Its strained three-membered ring makes it readily react with other substances.
Epoxide : A three-membered cyclic ether containing one oxygen atom and two carbon atoms. Ethylene oxide is the simplest epoxide, and its ring strain drives many reactions.
Ethylene glycol production : The industrial manufacture of ethylene glycol, commonly by hydrating ethylene oxide. This is a major route that turns ethylene oxide into a high-volume chemical.
Charles-Adolphe Wurtz : A French chemist whose nineteenth-century work included the preparation of ethylene oxide. Wurtz reported an early preparation of the compound in 1859.
Carcinogenicity of ethylene oxide : The capacity of ethylene oxide exposure to cause cancer, including through damage to genetic material. Long-term exposure is associated with increased cancer risk, shaping its regulation and use.
Steam sterilization : A sterilization method that uses saturated steam, usually under pressure, to destroy microorganisms. Steam is often preferred when devices tolerate heat and moisture; ethylene oxide suits sensitive materials.
Ring-opening reaction : A chemical reaction that breaks a ring in a molecule, producing an open-chain structure. Nucleophiles open ethylene oxide’s strained ring to form useful products.
Ethanolamine : A family of compounds containing both an amine group and a hydroxyl group, made industrially from ethylene oxide and ammonia. Ethylene oxide adds hydroxyethyl groups to ammonia to produce ethanolamines.
Chlorohydrin process : An industrial route to epoxides that forms a chlorohydrin intermediate and then removes hydrogen chloride. Ethylene oxide was historically produced by chlorohydrin chemistry before direct oxidation became dominant.
Ethylene oxide exposure : Contact with ethylene oxide by inhalation, skin absorption, or other routes. Exposure can occur in workplaces and near sterilization or manufacturing facilities.
Gamma irradiation : A sterilization method that uses gamma rays to inactivate microorganisms in products and packaging. It can sterilize packaged devices without gas residues, but may affect some materials.
