| Reactivity Profile | HEPTANOL is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. |

| Reinigungsverfahren | AEROBIC: 1-Heptanol degrades fast in aerobic biodegradation screening tests(1-5). In a 5-day BOD test using acclimated mixed cultures, 56.3% of theoretical BOD was consumed(1). Other tests show 30% of theoretical BOD was expended in 5 days(2) and 28.9% of theoretical BOD was expended in 1 day using 500 ppm of 1-heptanol and an activated sludge inoculum(3). An aerobic biodegradation rate constant of 0.124 1/hr(4), which corresponds to a half-life of 0.23 days(SRC), was determined in an aerobic screening test at pH 7 and 25 °C using an activated sludge inocula. In a similar screening test, the rate constant was measured to be 2.53X10-2 1/hr(5), which corresponds to a biodegradation half-life of 1.14 days(SRC).Do NOT let this chemical enter the environment. Cover the spilled material with absorbent. Collect leaking liquid in sealable containers. |

| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 74(SRC), determined from a water solubility of 1670 mg/L(2) and a regression-derived equation(3), indicates that 1-heptanol is expected to have high mobility in soil(SRC). Volatilization of 1-heptanol from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 1.88X10-5 atm-cu m/mole(4). 1-Heptanol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.216 mm Hg(5). 1-Heptanol has been demonstrated to be readily biodegradable in aerobic screening tests(6-10) and therefore should biodegrade in soil(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 74(SRC), determined from a water solubility of 1670 mg/L(2) and a regression-derived equation(3), indicates that 1-heptanol is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 1.88X10-5 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 2.2 days and 20 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 21(SRC), from its log Kow of 2.62(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). 1-Heptanol has been demonstrated to be readily biodegradable in aerobic screening tests(8-12) and therefore should biodegrade in water(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1-heptanol, which has a vapor pressure of 0.216 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-heptanol 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 28 hours(SRC), calculated from its rate constant of 1.36X10-11 cu cm/molecule-sec at 25 °C(3). |
