    Description

    Ethyl acetate (systematically, ethyl ethanoate, commonly abbreviated EtOAc or EA) is the organic compound with the formula CH3-COO-CH2-CH3, simplified to C4H8O2. This colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, decaffeinating tea and coffee, and cigarettes (see list of additives in cigarettes). Ethyl acetate is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent. The combined annual production in 1985 of Japan, North America, and Europe was about 400,000 tons. In 2004, an estimated 1.3M tons were produced worldwide.

    Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / Noxious)]: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. (ERG, 2016)

    5.3 Special protective actions for fire-fighters

    Wear self-contained breathing apparatus for firefighting if necessary.

    6.Accidental release measures

    6.1 Personal precautions, protective equipment and emergency procedures

    6.2 Environmental precautions

    Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Do NOT wash away into sewer. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

    6.3 Methods and materials for containment and cleaning up

    ACCIDENTAL RELEASE MEASURES. Personal precautions, protective equipment and emergency procedures: Use personal protective equipment. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapours accumulating to form explosive concentrations. Vapours can accumulate in low areas.; Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains.; Methods and materials for containment and cleaning up: Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulations.

    7.Handling and storage

    10.3 Possibility of hazardous reactions

    A very dangerous fire hazard when exposed to heat or flame.The vapour is heavier than air and may travel along the ground; distant ignition possible.ETHYL ACETATE is also sensitive to heat. On prolonged storage, materials containing similar functional groups have formed explosive peroxides. This chemical may ignite or explode with lithium aluminum hydride. It may also ignite with potassium tert-butoxide. It is incompatible with nitrates, strong alkalis and strong acids. It will attack some forms of plastics, rubber and coatings. It is incompatible with oxidizers such as hydrogen peroxide, nitric acid, perchloric acid and chromium trioxide. Violent reactions occur with chlorosulfonic acid. . SOCl2 reacts with esters, such as ethyl acetate, forming toxic SO2 gas and water soluble/toxic acyl chlorides, catalyzed by Fe or Zn (Spagnuolo, C.J. et al. 1992. Chemical and Engineering News 70(22):2.).

    12.2 Persistence and degradability

    AEROBIC: Ethyl acetate, present at 100 mg/L, reached 95% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). A review concluded that ethyl acetate is easily removed by biological treatment(2). Reported 5 day BOD values using a sewage inoculum range from 36-68% of theoretical(3-6) with the value being somewhat reduced in salt water(3). One investigator reported that ethyl acetate was completely degraded in 20 hr using activated sludge(7). In a bench-scale continuous-flow activated sludge reactor with an 8 hour retention time, 99.9% removal including 17% volatilization loss) was obtained, with 80% of the theoretical BOD(8). Ethyl acetate was 90% biooxidized in a 20-day BOD test using a filtered raw sewage seed; it was biooxidized 77% in a 28-day OECD closed-bottle test(9). A screening procedure that was systematically applied to a large number of organic chemicals ranked ethyl acetate as being completely biodegraded in a short time by general microorganisms(10). After a 5 hr lag, 43 to 53% of theoretical BOD was obtained in 50 to 70 hr(10). In screening tests, ethyl acetate, present at a concentration of 5 ppm, reached 26.6 and 57.1% of its theoretical BOD in 5 days using the standard dilution method and seawater dilution method, respectively(11). 99.9% removal of ethyl acetate was observed in a complete mix continuous-flow activated sludge system; 93% of this removal was attributed to biodegradation(12).

    12.3 Bioaccumulative potential

    An estimated BCF of 3 was calculated for ethyl acetate(SRC), using a log Kow of 0.73(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).

    12.4 Mobility in soil

    The Koc of ethyl acetate is estimated as 18(SRC), using a log Kow of 0.73(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that ethyl acetate is expected to have very high mobility in soil(SRC). A log Ki (snow surface/air (cu m/sq m)) of -3.69 has been reported for sorption to snow(4).

    12.5 Other adverse effects

    no data available

    13.Disposal considerations

    13.1 Disposal methods
