Ethylene oxide is the organic compound with the formula C2H4O. Its also called Oxirane, Epoxyethane, Dimethylene oxide and Eto. This colorless flammable gas with a faintly sweet odor is the simplest epoxide, a three-membered ring consisting of two carbon and one oxygen atom.

It is commonly handled and shipped as a refrigerated liquid. It is the chief precursor to ethylene glycol and other high-volume chemicals but is also used for medical sterilization. Ethylene oxide is produced by oxidation of ethylene with oxygen at circa 250 °C over a catalyst comprising metallic silver supported on alumina.

Ethylene oxide is toxic by inhalation. Symptoms of overexposure include headache and dizziness, progressing with increasing exposure to convulsions, seizure and coma. It is also an irritant to skin and the respiratory tract, and inhaling the vapors may cause the lungs to fill with fluid several hours after exposure.
