EtO brings serious risks of chemical burns to body tissues if a device, such as a plastic or rubber face mask, sterilized in EtO is not aerated (aeration cycle) after the sterilization cycle to allow the EtO absorbed during the cycle to elute from the mask, is … It is effective against most micro-organisms, including viruses. Eng. Ethylene oxide vapor may be initiated into explosive decomposition in absence of air [Hess, L. G., et al., Ind. , The entropy of ethylene oxide heat capacity from 14 to 285c vapor pressure heats of fusion and vaporization, J. Sci., 1978, 47, 668-669. and S. A. Baskett Jesus College, Oxford, UK. Ethylene oxide is also used as a sterilizing agent for medical equipment and a fumigating agent for spices. In smaller amounts, ethylene oxide is used as a pesticide and a sterilizing agent. Basis for listing ethylene oxide as known to the State to cause developmental toxicity, male reproductive toxicity, and female reproductive toxicity changed from Labor Code to 'Formally Required to Be Labeled or Identified' effective November 22, 2013. Ethylene oxide sterilization: effect of polymer structure and sterilization conditions on residue levels D. K. Gilding, A. M. Reed ICI'/University of Liverpool Joint Laboratory, Bioengineering Unit, PO Box 147, Liverpool L69 3BX, UK. Chem., 1950, 42, p. 1251]. The acute (short-term) effects of ethylene oxide in humans consist mainly of central nervous [ all data ] Walters and Smith, 1952 Chemical structure: This structure is also available as a 2d Mol file or as a computed 3d SD file The 3d structure may be viewed using Java or Javascript. Ethylene oxide is a colorless flammable gas at room temperature, with a faintly sweet odor; it is the simplest epoxide: a three-membered ring consisting of one oxygen atom and two carbon atoms. Ethylene oxide is a bactericidal, fungicidal, and sporicidal disinfectant. It is used primarily to produce other chemicals, including antifreeze. Because of its special molecular structure, ethylene oxide easily participates in addition reactions; e.g., opening its ring and thus easily polymerizing. Soc., 1949, 71, 2176. Part 2. Chao J., 1986 Chao J., Thermodynamic properties of key organic oxygen compounds in the carbon range C1 to C4. At room temperature, ethylene oxide is a flammable colorless gas with a sweet odor. Ramasamy R., Centrifugal distortion constants and thermodynamic functions of ethylene oxide, ethylene oxide-d4, and ethylene sulfide, Curr. Click hereto get an answer to your question ️ 1 - methyl ethylene oxide when treated with an excess of HBr produces: Public Notices Related to this Chemical. Hazard Summary . 75-21-8 . Ethylene Oxide . It is used as a fumigant for foodstuffs and textiles and as an agent for the gaseous sterilization of heat-labile pharmaceutical and surgical materials. Am. 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].
