- Environmental Bioconcentration: An estimated BCF of 2 was calculated for isopropyl acetate(SRC), using a water solubility of 29,000 mg/l(1,SRC) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests that bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 15(SRC), determined from a water solubility of 29,000 mg/l(2) and a regression-derived equation(3), indicates that isopropyl acetate is expected to have very high mobility in soil(SRC). Volatilization of isopropyl acetate from moist soil surfaces is expected to be important(SRC) given a Henry's Law constant of 2.78X10-4 atm-cu m/mole(4). The potential for volatilization of isopropyl acetate from dry soil surfaces may exist(SRC) based on a vapor pressure of 60.4 mm Hg(5,SRC). Isopropyl acetate was determined to have a 5 day BOD of 61% using a settled domestic wastewater seed, and BOD's of 72%, 74% and 76% after 10, 15 and 20 days, respectively(6). When the same inoculum was added to synthetic sea water, the 5, 10, 15 and 20 day BOD's were 14%, 39%, 43%, 49%, respectively(6). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 15(SRC), determined from a water solubility of 29,000 mg/l(2,SRC) and a regression-derived equation(3), indicates that isopropyl acetate is not expected to adsorb to suspended solids and sediment in water(SRC). Isopropyl acetate is expected to volatilize from water surfaces(3,SRC) based upon a Henry's Law constant of 2.78X10-4 atm-cu m/mole(4,SRC). Estimated volatilization half-lives for a model river and model lake are 6 hours and 5 days, respectively(3,SRC). A base-catalyzed second-order hydrolysis rate constant of 9.1X10-2 L/mol-sec(SRC) was estimated using a structure estimation method(2); this corresponds to half-lives of 2.4 years and 88 days at pH values of 7 and 8, respectively(2,SRC). According to a classification scheme(6), an estimated BCF of 2(3,SRC), from the water solubility(2,SRC), suggests that bioconcentration in aquatic organisms is low(SRC). Isopropyl acetate was determined to have a 5 day BOD of 61% using a settled domestic wastewater seed, and BODs of 72%, 74% and 76% after 10, 15 and 20 days, respectively(7).

- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), isopropyl acetate, which has a vapor pressure of 60.4 mm Hg at 25 °C(2,SRC), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase isopropyl acetate 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 about 4.6 days(3,SRC).
