화학적 성질
Diisopropyl ether(Isopropyl ether) is highly flammable, with a wide flammable range of 1.4%–21% in air. Boiling point is 156°F (68°C), flash point is 18°F (27°C), and ignition temperature is 830°F (443°C). Vapor density is 3.5, which is heavier than air. In addition to flammability, isopropyl ether is toxic by inhalation and a strong irritant, with a TLV of 250 ppm in air. Diisopropyl ether is an excellent solvent for natural oils, mineral oils, and waxes. It is used as an extracting agent and reaction medium in chemical and pharmaceutical syntheses.

| 환경 거동 | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 160(SRC), determined from a log Kow of 1.52(2) and a regression-derived equation(3), indicates that isopropyl ether is expected to have high mobility in soil(SRC). Volatilization of isopropyl ether from moist soil surfaces is expected to be important(3,SRC) given an estimated Henry's Law constant of 2.3X10-3 atm-cu m/mole(SRC), calculated from its water solubility(4) and vapor pressure(5). The potential for volatilization of isopropyl ether from dry soil surfaces may exist(SRC) based on a vapor pressure of 149 mm Hg(5). Isopropyl ether is not expected to hydrolyze in soil due to lack of hydrolyzable functional groups(3). Aqueous screening test data from studies using activated sludge or sewage inocula(6,7) suggest that isopropyl ether may be resistant to biodegradation in environmental media(SRC). Many ethers are known to be resistant to biodegradation(8).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 160(SRC), determined from a log Kow of 1.52(2) and a regression-derived equation(3), indicates that isopropyl ether is not expected to adsorb to suspended solids and sediment in water(SRC). Isopropyl ether is expected to volatilize rapidly from water surfaces(3,SRC) based on an estimated Henry's Law constant of 2.3X10-3 atm-cu m/mole(SRC), calculated from its water solubility(4) and vapor pressure(5). Estimated volatilization half-lives for a model river and model lake are 3 hours and 4 days, respectively(3,SRC). Isopropyl ether is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(3). Isopropyl ether will not significantly photooxidize via reaction with photochemically produced hydroxyl radicals in the water(6). According to a classification scheme(7), an estimated BCF of 8(3,SRC), from isopropyl ether's log Kow(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Isopropyl ether may be resistant to biodegradation in environmental media based upon screening test data from studies using activated sludge or sewage inocula(8,9,SRC). Many ethers are known to be resistant to biodegradation(10).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), isopropyl ether, which has a vapor pressure of 149 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase isopropyl ether 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 21 hours(3,SRC). The half-life for the reaction of isopropyl ether with nitrate radicals is estimated as 9 seconds(4,SRC). Direct photolysis will not be an important removal process since aliphatic ethers do not absorb light at wavelengths >290 nm(5). |

| Effluent Concentrations | Isopropyl ether has been detected in 10 out of 63 samples of industrial effluents collected from a wide variety of industries across the USA (dates not reported)(1). Six of the positive samples contained <10 ug/L isopropyl ether, 3 samples contained 10-100 ug/L and 1 sample contained >100 ug/L(1). Samples of landfill gas from an unspecified landfill which had for more than 15 months accepted municipal and industrial solid wastes and unspecified liquid wastes contained 220 mg/cu m isopropyl ether(2). |
| Medical Surveillance | Employees should be screened for history of certain medical conditions /chronic respiratory disease or skin disease/ which might place the employee at increased risk from isopropylether exposure. In persons with impaired pulmonary function, especially those with obstructive airway diseases, the breathing of isopropylether might cause exacerbation of symptoms due to its irritant properties. Isopropylether is a defatting agent and can cause dermatitis on prolonged exposure. Persons with existing skin disorders may be more susceptible to the effects of this agent. Any employee developing the above-listed conditions should be referred for further medical examination. /Chronic respiratory disease or skin disease/ |
| Soil Adsorption/Mobility | The Koc of isopropyl ether is estimated as approximately 160(SRC), using a log Kow of 1.52(1) and a regression-derived equation(2,SRC).

Repeated skin contact would be expected to cause dermatitis.... a group of subjects exposed for 15 minutes at 500 ppm did not consider the exposure to be irritating.

용도
개요
Diisopropyl ether [108-20-3], also known as 2-isopropoxyisopropane or isopropyl ether, is a clear, colorless, mobile, highly flammable liquid with a characteristic ethereal odor. Its solubility in water is low, but it is soluble in organic solvents and readily forms explosive peroxides. It has a higher boiling point, a lower vapor pressure, and a lower water solubility than diethyl ether, which means that diisopropyl ether can be recovered without significant loss after use as a solvent or as an extractant.
용도
Isopropyl ether is used as a solvent for oils,waxes, resins, and dyes; and as a varnishremover.
일반 설명
Diisopropyl ether appears as a clear colorless liquid with an ethereal odor. Flash point -18°F. Less dense than water. Vapors heavier than air.
제조 및 합성 방법
제조 방법
Diisopropyl ether can be prepared by liquid-phase dehydration of 2-propanol at 130 – 190°C and 1.96– 7.85 MPa over acidic catalysts containing aluminum.
