WebAug 12, 2024 · Properties. Ethylene oxide (EtO) is a colorless and flammable gas with a sweet, fruity odor at room temperature. It dissolves in water, alcohol, and most water-miscible organic solvents. It has an estimated half-life in air ranging from 69-149 days, while its half-life in water ranges from 12 to 14 days in sterile, deionized, and natural river ... The process consists of three major steps: synthesis of ethylene chlorohydrin, dehydrochlorination of ethylene chlorohydrin to ethylene oxide and purification of ethylene oxide. Those steps are carried continuously. See more Ethylene oxide is an organic compound with the formula C2H4O. It is a cyclic ether and the simplest epoxide: a three-membered ring consisting of one oxygen atom and two carbon atoms.
