Ethylene oxide is a colorless gas at room temperature and a colorless liquid below 51�F (10.7�C). It is shipped as a liquefied, compressed gas. Both the gas and liquid are potential fire and explosion hazards. Ethylene oxide has a sweet, ether-like odor at air concentrations above 500 ppm. Ethylene oxide is soluble in water and organic solvents. Synonyms include dimethylene oxide, 1,2-epoxyethane, EtO, EO, ethene oxide, and oxirane.
When a single dose of 2 mg labelled ethylene oxide in propanediol/kg body weight was applied intraperitoneally to rats, 43% of the administered radioactivity was excreted in the urine within 50 h (41% within 24 h) of exposure, 9% as S-(2- hydroxyethyl)cysteine and 33% as N-acetyl- S-(2-hydroxyethyl) cysteine, both products of glutathione conjugation. Via the lungs, 1.5% was excreted as carbon dioxide and 1% as unmetabolized ethylene oxide (Jones & Wells, 1981). The involvement of glutathione-epoxide- S-transferase (EC 4.4.1.7) has not been investigated further. In vitro glutathione conjugation of the homologue propylene oxide was shown to proceed only in the presence of an enzyme (Fjellstedt et al., 1973). In rabbits, no effect was found on liver- and blood-glutathione levels, after 12 weeks of exposure to concentrations of ethylene oxide at 18, 90, or 450 mg/m3, for 5 days per week, 6 h per day (Yager & Benz, 1982). As ethylene oxide can react with chloride ions, and this reaction is acid ...
AbstractIn the ethylene glycol generation unit of petrochemical plants, first a reaction of ethylene oxide takes place which is then followed by other side reactions. These reactions include water absorption with ethylene oxide, which leads to the generation of formaldehyde and acetaldehyde. Over the lifetime of the alpha-alumina-based silver catalyst there is an increase in side reactions, increasing the amount of the formaldehyde and acetaldehyde generated by the ethylene oxide reactor which leads to reduced MEG product purity. Given the need of a petrochemical complex to further strip the aldehyde (formaldehyde and acetaldehyde) to increase the quality of the MEG and increase the lifetime of the alpha-alumina-based silver catalyst, resin beds are designed and their surface absorption capacity is investigated to optimize aldehyde (formaldehyde and acetaldehyde) removal in the recirculating water flow of the ethylene oxide unit. Experiments show that the ion exchange system based on strong anionic
Erie, Pennsylvania 16501. Dear Mr. Rohleder:. This is in response to your inquiry of September 6, regarding procedures for ethylene oxide (EtO) spills and ethylene oxide disposal.. All spills should be immediately cleaned up with non-combustible adsorbent material that is readily available on the market. OSHA does not specify any one type of spill cleaning and adsorbing material or equipment; however, water should be used to wash down spill areas.. Since EtO is a gas at room temperature, you are dealing with the gaseous form of EtO predominantly in your work air that will not produce a spill. For example, when EtO leaks from a high pressure vessel, the EtO would be in a liquid form for only a short period of time as it leaks into the air. It then quickly equilibrates with the room air to form a gas. Both the gaseous and, when necessary, the liquid phase of EtO exposure must be taken into consideration.. See enclosed excerpts from appendices of 29 CFR 1910.1047 (Ethylene Oxide) which includes ...
BD Bard came under fire last summer, when a report was released correlating elevated cancer rates in the Covington area with the companys use of ethylene oxide, a gas that made the environmantal Protection Agencys list of gases that definitely cause cancer. In January, BD Bard was was ordered to pay the cities of Madison and Covington $65,000 each due to the companys previous violations in the production of ethylene oxide. Madison is home to one of the seven industrial plants in Georgia that use ethylene oxide. The spotlight fell on Madisons BD Bard plant after its sister plant in Covington was forced to shut down by the state when local officials detected elevated ethylene oxide emissions in the air-as high as 5,600 pounds a year. According to a court ruling in the case between BD Bard and the Georgia Environmental Protection Division (GEPD), BD Bard is mandated To mitigate the impact of these issues, BD Bard shall provide a grant of $65,000 to the city of Covington, Ga., and a grant of ...

EPA is addressing ethylene oxide based on the results of the latest National Air Toxics Assessment (NATA), which identified the chemical as a potential concern in several areas across the country. NATA is the Agencys nationwide air toxics screening tool, designed to help EPA and state, local and tribal air agencies identify areas, pollutants or types of sources for further examination.. The 2014 NATA uses emissions data from the latest National Emissions Inventory (2014 is the most recent data available), along with the latest scientific information on air toxics and health, to estimate long-term air toxics exposures and potential public health risk in census tracts across the United States.. NATA estimates long-term risks - those that may occur from breathing air containing elevated levels of air toxics continuously for many decades. It does not estimate short-term (acute) or intermediate risks. However, based on an examination of available data, EPA does not expect ethylene oxide levels in ...

TY - JOUR. T1 - Stability of silicon and titanium carbide suspensions in electrolyte, poly(ethylene oxide), and PEO-surfactant solutions. AU - Bárány, S.. AU - Eremenko, Boris V.. AU - Malysheva, Mariya L.. PY - 2004/7/1. Y1 - 2004/7/1. N2 - It has been shown that the coagulation values of counterions for SiC and TiC suspensions with particle radius from 0.5 to 5 μm obey a z 2.5-3.5 law and there is an insufficient change in the critical concentration of 1-1 electrolytes (CCE) when the surface potential of particles increases more than two times. Also, the CCE values hardly depend on the position of counterions in the lyotropic sequence. This is explained by aggregation of SiC and TiC particles at a secondary minimum, which is proved by calculations of the potential curves of interparticle interactions using the DLVO theory. The adsorption of poly(ethylene oxide) on the surfaces studied does not cause - in contradiction to dispersions with smaller particles - an unlimited growth in the ...

The drag reducing effect of poly(ethylene oxide) additives on blunt bodies in water was investigated by examining the behavior of a sphere in both subcritical and supercritical Reynolds number regions. Drop tests were conducted in water and in concentrations of poly(ethylene oxide) WSR 301 ranging in concentration from 50 wppm to 1000 wppm. Reduction in drag was noted for all concentrations in the Reynolds number range of 40,000 to 350,000. A critical Reynolds number of 450,000 was observed for dilute solutions (50 and 100 wppm), while more concentrated solutions exhibited a uniformly decreasing drag. These results are explained by examining the interaction of profile and friction drag, together with the effects of polymer additives upon wake diameter size. (Author)(*UNDERWATER VEHICLES
A six-dimensional potential energy hypersurface (PES) for two interacting rigid ethylene oxide (C{sub 2}H{sub 4}O) molecules was determined from high-level quantum-chemical ab initio calculations. The counterpoise-corrected supermolecular approach at the MP2 and CCSD(T) levels of theory was utilized to determine interaction energies for 10178 configurations of two molecules. An analytical site-site potential function with 19 sites per ethylene oxide molecule was fitted to the interaction energies and fine tuned to agree with data for the second acoustic virial coefficient from accurate speed of sound measurements. The PES was validated by computing the second virial coefficient, shear viscosity, and thermal conductivity. The values of these properties are substantiated by the best experimental data as they tend to fall within the uncertainty intervals and also obey the experimental temperature functions, except for viscosity, where experimental data are insufficient. Due to the lack of reliable ...

State lawmakers are debating two bills, one that would ban the use of ethylene oxide in densely populated areas or near schools, and another that would give home rule to communities.
Ethylene oxide (EtO) is a colorless, flammable gas. At very high levels, it smells like ether. EPA has classified ethylene oxide as an air toxic. It is a chemical ingredient used in solvents, antifreeze, textiles, and glues. It is also used to sterilize surgical equipment - particularly plastics that are difficult to sterilize with steam.. EPAs most recent National Air Toxics Assessment identified several locations that may have higher cancer risks from long-term exposure to ethylene oxide. Most of these places are close to where ethylene oxide is made or to industries that use the chemical.. Even though none of these locations are in Washington, Ecologys air quality monitoring station near downtown Seattle has found ethylene oxide. Based on this and on studies from other areas, we are following this as an emerging health concern.. ...
