SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal and plant life; and conformance with environmental and public health regulations.

Strong oxidizing agents.

Perfluorobutyl ethylene's production and use in the manufacture of fluorinated polymers(1) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 7800(SRC), determined from a structure estimation method(2), indicates that perfluorobutyl ethylene is expected to be immobile in soil(SRC). Volatilization of perfluorobutyl ethylene from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 110 atm-cu m/mole(SRC), using a fragment constant estimation method(3). However, adsorption to soil is expected to attenuate volatilization(SRC). Perfluorobutyl ethylene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 238 mm Hg at 20 °C(4). Biodegradation data in soil were not available(SRC, 2011).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 7800(SRC), determined from a structure estimation method(2), indicates that perfluorobutyl ethylene is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 110 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 4.9 hours and 6.2 days, respectively(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The volatilization half-life from a model pond is about 80 days when adsorption is considered(5). According to a classification scheme(6), an estimated BCF of 370(SRC), from an estimated log Kow of 4.4(7) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is high, provided the compound is not metabolized by the organism(SRC). Biodegradation data in water were not available(SRC, 2011).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), perfluorobutyl ethylene, which has a vapor pressure of 238 mm Hg at 20 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase perfluorobutyl ethylene 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 19 hours(SRC), calculated from its rate constant of 2.0X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). The rate constant for the vapor-phase reaction of perfluorobutyl ethylene with ozone has been estimated as 1.8X10-18 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3); the half-life for this reaction in air is about 6.5 days(4). Perfluorobutyl ethylene does not contain chromophores that absorb at wavelengths >290 nm(5), and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

The rate constant for the vapor-phase reaction of perfluorobutyl ethylene with photochemically-produced hydroxyl radicals has been estimated as 2.0X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 19 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). The rate constant for the vapor-phase reaction of perfluorobutyl ethylene with ozone has been estimated as 1.8X10-18 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(1). This corresponds to an atmospheric half-life of about 6.5 days at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(2). Perfluorobutyl ethylene is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). Perfluorobutyl ethylene does not contain chromophores that absorb at wavelengths >290 nm(3), and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

An estimated BCF of 370 was calculated in fish for perfluorobutyl ethylene(SRC), using an estimated log Kow of 4.4(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not metabolized by the organism(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of perfluorobutyl ethylene can be estimated to be 7800(SRC). According to a classification scheme(2), this estimated Koc value suggests that perfluorobutyl ethylene is expected to be immobile in soil.

The Henry's Law constant for perfluorobutyl ethylene is estimated as 110 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that perfluorobutyl ethylene is expected to volatilize rapidly from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 4.9 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 6.2 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The volatilization half-life from a model pond is about 80 days when adsorption is considered(3). Perfluorobutyl ethylene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 238 mm Hg at 20 °C(4).
