WebAug 29, 2014 · Description. Ethylene oxide is also called oxirane. It is a cyclic ether that is a colorless flammable gas at room temperature, with a faintly sweet odor. It is the simplest epoxide known. Because of its special molecular structure, ethylene oxide easily participates in addition reactions; e.g., opening its ring and thus easily polymerizing. Ethylene oxide is a colorless gas at 25 °C (77 °F) and is a mobile liquid at 0 °C (32 °F) – viscosity of liquid ethylene oxide at 0 °C is about 5.5 times lower than that of water. The gas has a characteristic sweet odor of ether, noticeable when its concentration in air exceeds 500 ppm. Ethylene oxide is readily soluble in water, … See more Ethylene oxide is an organic compound with the formula C2H4O.
