Reactivity AlertsHighly Flammable
Reactivity ProfileEthers, such as DIOXOLANE, can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.

환경 거동TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 15(SRC), determined from a log Kow of -0.37(2) and a regression-derived equation(3), indicates that 1,3-dioxolane is expected to have very high mobility in soil(SRC). Volatilization of 1,3-dioxolane from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 2.45X10-5 atm-cu m/mole(4). 1,3-Dioxolane is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 79 mm Hg(5). Biodegradation data were not available(SRC, 2006).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 15(SRC), determined from a log Kow of -0.37(2) and a regression-derived equation(3), indicates that 1,3-dioxolane is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 2.45X10-5 atm-cu m/mole(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 33 hours and 13 days, respectively(SRC). The aquatic oxidation rate for the reaction of 1,3-dioxolane with photochemically produced hydroxyl radicals has been experimentally determined to be 4.0X10+9 L/mol-s (pH not stated)(5). Based on this rate and a hydroxyl radical concn of 1X10-17 mol/L in water under continuous sunlight(6), the half-life for the aquatic oxidation of 1,3-dioxolane can be estimated to be 200 days(SRC). According to a classification scheme(7), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Biodegradation data were not available(SRC, 2006).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1,3-dioxolane, which has a vapor pressure of 79 mm Hg at 20 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1,3-dioxolane is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 37 hours(SRC), calculated from its rate constant of 1.04X10-11 cu cm/molecule-sec at 25 deg(3).

TSCA Test SubmissionsThe ability of trimethyl phosphite to induce morphological transformation in the C3H/10T 1/2 mouse cell line (Cell Transformation Assay) was evaluated. Based on preliminary toxicity tests (exposure time=18 hrs), trimethyl phosphite in acetone was tested at concentrations of 0, 128, 256, 512, 1024 and 2048 ul/ml, with cell survival ranging from 71.6% to 40.9&% at 128 and 1024 ul/ml, respectively. Trimethyl phosphite did not induce transformation at any of the concentrations tested in this study.In a one-generation reproduction study, male Charles River rats (5/group) were orally exposed to 1,3-dioxolane in their drinking water at concentrations of 0, 0.5 or 1.0% for 90 days prior to mating with previously untreated females (10/group, 2/male). Treatment continued through the mating period. Dams and pups were examined with respect to survival and body weight through postpartum day (PD) 21 and the animals were retained for further experimentation. Significant differences were observed between treated and control animals in the following: decreased maternal body weights (high-dose group on PD 1 and 4, male weights not reported), decreased rates of coupling and parturition, and increased number of stillborn pups, (both treatment levels), decreased survival of pups (both treatment groups, zero 24-hour survival rate for high-dose group pups), and decreased numbers of pups (high-dose group). No significant differences were observed between treated and control animals in the following: parental mortality, fecundity or female fertility indices, gross external abnormalities, and pup body weights.In a one-generation reproduction study, male Charles River rats (5/control and 0.5% groups, 4/1.0% group) were orally exposed to 1,3-dioxolane in their drinking water at concentrations of 0, 0.5 or 1.0% for 90 days prior to mating with previously untreated females (10/control and 0.5% groups, 8/1.0% group, all groups 2 females/male). Treatment continued through the mating period for both sexes, and for the dams also through gestation, lactation and the 10-day rest period after weaning of the F1a pups and before the second mating with untreated, proven males. There were no treatments during the remainder of these tests. Dams and F1b pups were examined with respect to survival and body weight through postpartum day 21, the F1b pups were retained for further testing, and the dams were sacrificed and subjected to histopathological examination. Significant differences observed between treated and control animals in the following: decreased fecundity index, incidence of parturition, and female fertility index (both treatment levels), and decreased pup survival (low-dose group at days 12 and 21, high-dose group at day 21). No significant differences were observed between treated and control animals in the following: parental mortality, male fertility index, number of pups born, stillborn, cannibalized, or viable pups (at birth or on lactation days 1, 4, 12 and 21), maternal or pup body weights, gross maternal pathologic examination, weights maternal organs (adrenals, both gonads, liver, pituitary, and uterus), and maternal histopathologic examination.In a one-generation reproduction study, male Charles River rats (5/group) were orally exposed to dioxolane (1,3-dioxolane) in their drinking water at concentrations of 0, 0.01, 0.03 or 0.10% for 90 days prior to mating with previously untreated females (10/group, 2 females/male). Treatment continued through mating, gestation and lactation. Dams and pups were examined with respect to survival and body weight through postpartum day (PD) 21 and the animals were retained for further experimentation. A significant difference was observed between treated and control animals in decreased male pup body weight (low-dose group on lactation day 21). No significant differences were observed between treated and control animals in the following: maternal mortality, mating and fertility indices, male and female fertility, incidence of parturition, gross abnormalities in pups, number of pups delivered stillborn or viable, or cannibalized (lactation days 1, 4, 12 or 21), survival indices, female pup body weight, and female parental body weight.For more TSCA Test Submissions (Complete) data for 1,3-DIOXOLANE (11 total), please visit the HSDB record page.
Artificial Pollution Sources1,3-Dioxolane's production and use as a low-boiling solvent and extractant for oils, fats, waxes, dyes and cellulose derivatives(1) may result in its release to the environment through various waste streams(SRC).
Environmental BioconcentrationAn estimated BCF of 3 was calculated in fish for 1,3-dioxolane(SRC), using a log Kow of -0.37(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 1,3-dioxolane is 2.45X10-5 atm-cu m/mole(1). This Henry's Law constant indicates that 1,3-dioxolane is expected to volatilize from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 33 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 13 days(SRC). 1,3-Dioxolane's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 1,3-Dioxolane is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 79 mm Hg(3).

Respiratory and neuromuscular abnormalities were the immediate responses to the test material during the exposure and during the four hour-post-exposure observation periods. Severity and incidences of these findings followed a concentration-related pattern. During the 14-day post-exposure observation period, all survivors appeared to recover by day 4. Most surviving animals appeared to regain pre-exposure body weights by Day 7 and showed normal weight gain patterns during the second week. Necropsy findings revealed high incidences of lung and liver discoloration as well as bladders distended with fluid and gastrointestinal tracts distended with gas in animals dying prior to scheduled sacrifice.

Environmental Abiotic DegradationThe rate constant for the vapor-phase reaction of 1,3-dioxolane with photochemically-produced hydroxyl radicals has been measured as 1.04X10-11 cu cm/molecule-sec at 25 °C(1). This corresponds to an atmospheric half-life of about 37 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(2). The aquatic oxidation rate for the reaction of 1,3-dioxolane with photochemically produced hydroxyl radicals has been experimentally determined to be 4.0X10+9 L/mol-s (pH not stated)(3). Based on this rate and a hydroxyl radical concn of 1X10-17 mol/L in water under continuous sunlight(4), the half-life for the aquatic oxidation of 1,3-dioxolane can be estimated to be 200 days(SRC). 1,3-Dioxolane is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(5).
대기 기준This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Dioxilane is produced, as an intermediate or a final product, by process units covered under this subpart.
