[ all data ] Walters and Smith, 1952 Ethylene oxide vapor may be initiated into explosive decomposition in absence of air [Hess, L. G., et al., Ind. 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]. It is used primarily to produce other chemicals, including antifreeze. Chao J., 1986 Chao J., Thermodynamic properties of key organic oxygen compounds in the carbon range C1 to C4. Eng. In smaller amounts, ethylene oxide is used as a pesticide and a sterilizing agent. , The entropy of ethylene oxide heat capacity from 14 to 285c vapor pressure heats of fusion and vaporization, J. Because of its special molecular structure, ethylene oxide easily participates in addition reactions; e.g., opening its ring and thus easily polymerizing. Am. It is effective against most micro-organisms, including viruses. The acute (short-term) effects of ethylene oxide in humans consist mainly of central nervous Ethylene oxide is also used as a sterilizing agent for medical equipment and a fumigating agent for spices. Public Notices Related to this Chemical. 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. 75-21-8 . At room temperature, ethylene oxide is a flammable colorless gas with a sweet odor. Chem. Chem., 1950, 42, p. 1251]. 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 … Sci., 1978, 47, 668-669. Ethylene oxide is a bactericidal, fungicidal, and sporicidal disinfectant. Ethylene Oxide . Ramasamy R., Centrifugal distortion constants and thermodynamic functions of ethylene oxide, ethylene oxide-d4, and ethylene sulfide, Curr. Soc., 1949, 71, 2176. 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. Part 2. Hazard Summary . The major use of ethylene oxide is as a chemical intermediate in the manufacture of ethylene glycol. 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. 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.
