Dose-rate effects of ethylene oxide exposure on developmental toxicity In risk assessment, evaluating a health effect at a duration of exposure that is untested involves assuming that equivalent multiples of concentration (C) ... E,Weller - 《Toxicological Sciences》 被引量: 47发表: 1999年 SUBLETH...
Pressurized hydration had a high demand for the molar ratio of ethylene oxide over water which is higher than 1:6, to reduce the side reaction of producing the ether with the reaction temperature being at 150 °C and the pressure being 147kPa with hydration generating ethylene glycol. ...
Sterilizing medical devices with ethylene oxide (EO) is a common practice primarily due to its extensive material compatibility. The main side effect of using EO as a sterilization agent is that it can leave a residue on the devices being processed. The residues that may be found after ...
Ethylene oxide (EO) is a key chemical intermediate produced almost exclusively from petrochemically derived ethylene. Currently, EO manufacturing involves epoxidation of ethylene with O2 over Ag/Al2O3 - one of the highest CO2-emitting processes in the chemical sector (Boulamanti and Moya, 2017)....

Ethylene oxide is an alkylating agent; it has irritating, sensitizing and narcotic effects. Chronic exposure to ethylene oxide is also mutagenic. The International Agency for Research on Cancer (IARC) classifies ethylene oxide into group 1, meaning it is a proven carcinogen (IARC, 1999)...
it is essential to explore the effects of different limiting factors for the alteration of product formation. This section summarizes main aspects based on electrolytes, including the effects of pH, anions, cations and additives, as well as the effects of catalyst surface potential and crystal surfa...
Potential Exposure Ethylene is used in production of fabricated plastics, antifreeze; making fibers; to manufacture ethylene oxide, polyethylene for plastics, alcohol, mustard gas and other organics. It is used to accelerate ripening of fruit; as an anesthetic; and for oxyethylene welding and cutting...
Poly (ethylene oxide) (PEO) (long linear chain polymer) are expected to confer high flexibility to the CA matrix [25]. Also, FDA has approved PEO for use in foods and pharmaceuticals because of its spinnability, biodegradability, biocompatibility, and lack of toxicity [25]. PEO/zein ...
the mass was ground with a pestle in its hot state and again the vessel was kept at 100°C. This hot material was cooled to room temperature and again it was ground. This compound was used as filler. TheEPDMrubber was mixed with zinc oxide (ZnO) and the stearic acid modified clay was...
