    10.Stability and reactivity

    10.1 Reactivity

    no data available

    10.2 Chemical stability

    It is slowly oxidized by action of air, moisture, and light, with formation of peroxides.

    10.3 Possibility of hazardous reactions

    When shaken under absolutely dry conditions ether can generate enough static electricity to start a fire.The vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated.Occasional explosions have occurred when aluminum hydride was stored in ether. The explosions have been blamed on the presence of carbon dioxide impurity in the ether, [J. Amer. Chem. Soc. 70:877(1948)]. Diethyl ether and chromium trioxide react violently at room temperature. Solid acetyl peroxide in contact with ether or any volatile solvent may explode violently. A 5-gram portion in ether detonated while being carried, [Chem. Eng. News 27:175(1949)]. Nitrosyl perchlorate ignites and explodes with diethyl ether. A mixture of ether and ozone forms aldehyde and acetic acid and a heavy liquid, ethyl peroxide, an explosive, [Mellor 1:911(1946-1947)].

    • Toxicity to algae: no data available
    • Toxicity to microorganisms: no data available

    12.2 Persistence and degradability

    AEROBIC: Diethyl ether has been included in a list of compounds which were not biodegraded in a relatively short time either in screening tests which utilized sewage sludge inocula or soil inocula(1). Many ethers are known to be resistant to biodegradation(1). The 5-day biological oxygen demand measured for diethyl ether in screening tests ranged from 0%(2,3) to approximately 1.1%(2) in studies using the standard dilution technique with sewage inocula and 0% in a screening study using an activated sludge inoculum(4). A lag time of >10 days was observed in the latter study with activated sludge(4). In a study which used the seawater dilution method with a sewage inoculum, 0% theoretical BOD was observed over a 5-day period(3). No change was observed in the biological oxygen demand in tests of a semi-continuous activated sludge biological treatment simulator which tested for the removal of diethyl ether at a concn of 200 to 800 ppm in a domestic sewage feed over a period of 24 hours(5). A biodegradation study of diethyl ether, based on TOC measurements (GC analysis), using an activated sludge seed and an initial diethyl ether concn of 100 mg/L, indicated 2.5% (6.5%) biodegradation over a period of 4 weeks(6).

    12.3 Bioaccumulative potential

    BCF values of 0.9 to 1.4 and <1.7 to 9.1 were measured for carp exposed to 500 and 50 ug/L of diethyl ether over the course of a 6 week incubation period(1). According to a classification scheme(2), these BCFs suggest bioconcentration in aquatic organisms is low.

    12.4 Mobility in soil

    The Koc of diethyl ether is estimated as approximately 73(SRC), using a log Kow of 0.89(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that diethyl ether is expected to have high mobility in soil(SRC). A vapor-phase partition coefficient of 15.49 was measured for diethyl ether at 30°C in the silt and clay size fraction of a calcareous soil (1.2% organic carbon w/w) from Southern Nevada at 52% relative humidity(4).

    12.5 Other adverse effects

    no data available

    13.Disposal considerations

    13.1 Disposal methods
