처리 방법SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

용도

용도

According to HSDB , EGME has been used in the manufacture of plastics and lacquers and also in the production of protective coatings.

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), ethylene glycol monovinyl ether, which has an estimated vapor pressure of 2.2 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere(SRC). Vapor-phase ethylene glycol monovinyl ether is degraded in the atmosphere by reactions with photochemically-produced hydroxyl radicals and ozone(SRC)
the half-lives for these reactions in air are estimated to be 2.8 and 31 hrs, respectively(SRC), calculated from their rate constants of 4.5X10-11 cu cm/molecule-sec and 0.88X10-17 cu cm/molecule-sec at 25 °C, respectively(SRC), that were derived using a structure estimation method(3).
유해 작용Neurotoxin - Acute solvent syndrome
Soil Adsorption/MobilityUsing a structure estimation method based on molecular connectivity indices(1), the Koc for ethylene glycol monovinyl ether can be estimated to be 1(SRC). According to a classification scheme(2), this estimated Koc value suggests that ethylene glycol monovinyl ether is expected to have very high mobility in soil(SRC).
Artificial Pollution SourcesEthylene glycol monovinyl ether's production and use in the manufacture of plastics and lacquers(1) may result in its release to the environment through various waste streams(SRC).
Environmental BioconcentrationAn estimated BCF of 3 was calculated for ethylene glycol monovinyl ether(SRC), using an estimated log Kow of -0.55(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Volatilization from Water/SoilThe Henry's Law constant for ethylene glycol monovinyl ether is estimated as 2.5X10-7 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that ethylene glycol monovinyl ether is expected to be essentially nonvolatile from water surfaces(2). The potential for volatilization of ethylene glycol monovinyl ether from dry soil surfaces may exist(SRC) based upon an estimated vapor pressure of 2.2 mm Hg(SRC), determined from a fragment constant method(3).
Environmental Abiotic DegradationThe rate constant for the vapor-phase reaction of ethylene glycol monovinyl ether with photochemically-produced hydroxyl radicals has been estimated as 4.5X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 2.8 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). The rate constant for the vapor-phase reaction of ethylene glycol monovinyl ether with photochemically-produced ozone has been estimated as 0.88X10-17 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 31 hours at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(2). Ethylene glycol monovinyl ether is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(3) nor to directly photolyze due to the lack of absorption in the environmental UV spectrum (>290 nm)(SRC).
Probable Routes of Human ExposureOccupational exposure to ethylene glycol monovinyl ether may occur through inhalation and dermal contact with this compound at workplaces where ethylene glycol monovinyl ether is produced or used. (SRC)
Environmental Fate/Exposure SummaryEthylene glycol monovinyl ether's production and use in the manufacture of plastics and lacquers may result in its release to the environment through various waste streams. If released to air, an estimated vapor pressure of 2.2 mm Hg at 25 °C indicates ethylene glycol monovinyl ether will exist solely as a vapor in the ambient atmosphere. Vapor-phase ethylene glycol monovinyl ether will be degraded in the atmosphere by reactions with photochemically-produced hydroxyl radicals and ozonethe half-lives for these reactions in air are estimated to be 2.8 and 31 hrs, respectively. If released to soil, ethylene glycol monovinyl ether is expected to have very high mobility based upon an estimated Koc of 3.2. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 2.8X10-7 atm-cu m/mole. If released into water, ethylene glycol monovinyl ether is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. An estimated BCF of 3.2 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. Occupational exposure to ethylene glycol monovinyl ether may occur through inhalation and dermal contact with this compound at workplaces where ethylene glycol monovinyl ether is produced or used.
