3,3,3-Trifluoro-1-propene's production and use in the manufacture of fluorine-containing silicones used in hydraulic fluids(1), may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 97(SRC), determined from a structure estimation method(2), indicates that 3,3,3-trifluoro-1-propene is expected to have high mobility in soil(SRC). Rapid volatilization of 3,3,3-trifluoro-1-propene from moist soil surfaces is expected(SRC) given an estimated Henry's Law constant of 0.76 atm-cu m/mole(SRC), developed using a fragment constant estimation method(3). 3,3,3-Trifluoro-1-propene is expected to volatilize rapidly from dry soil surfaces based on a vapor pressure of 4,393 mm Hg(SRC) at 25 °C(4). Highly chlorinated/fluorinated compounds are not expected to biodegrade rapidly(5).|AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 97(SRC), determined from a structure estimation method(2), indicates that 3,3,3-trifluoro-1-propene is not expected to adsorb to suspended solids and sediment in water(SRC). 3,3,3-Trifluoro-1-propene is expected to rapidly volatilize from water surfaces(3,SRC) based on an estimated Henry's Law constant of 0.76 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Estimated half-lives for a model river and model lake are 3 and 93 hours, respectively(3,SRC). According to a classification scheme(5), an estimated BCF value of 23(3,SRC), from an estimated log Kow of 2.09(6,SRC), suggests that bioconcentration in aquatic organisms is low(SRC). Highly chlorinated/fluorinated compounds are not expected to biodegrade rapidly(7).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 3,3,3-trifluoro-1-propene, which has an extrapolated vapor pressure of 4,393 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 3,3,3-trifluoro-1-propene is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals and ozone molecules(SRC); the half-lives for these reactions in air are estimated to be about 19 and 156 hours respectively(3,SRC).

The rate constant for the vapor-phase reaction of 3,3,3-trifluoro-1-propene 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,SRC). This corresponds to an atmospheric half-life of about 19 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1,SRC). The rate constant for the vapor-phase reaction of 3,3,3-trifluoro-1-propene with ozone has been estimated as 1.8X10-18 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1,SRC). This corresponds to an atmospheric half-life of about 156 hours at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(1,SRC). 3,3,3-Trifluoro-1-propene is not expected to undergo hydrolysis in the environment due to the lack of functional groups to hydrolyze.

An estimated BCF value of 23 was calculated for 3,3,3-trifluoro-1-propene(SRC), using an estimated log Kow of 2.09(1,SRC) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 3,3,3-trifluoro-1-propene can be estimated to be about 97(SRC). According to a recommended classification scheme(2), this estimated Koc value suggests that 3,3,3-trifluoro-1-propene is expected to have high mobility in soil(SRC).

The Henry's Law constant for 3,3,3-trifluoro-1-propene is estimated as 0.76 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This value indicates that 3,3,3-trifluoro-1-propene will volatilize rapidly from water surfaces(2,SRC). 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) is estimated as approximately 3 hours(2,SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec) is estimated as approximately 96 hours(2,SRC). 3,3,3-Trifluoro-1-propene's Henry's Law constant(1,SRC) indicates that volatilization from moist soil surfaces is expected(SRC). 3,3,3-Trifluoro-1-propene is expected to volatilize rapidly from dry soil surfaces based on an extrapolated vapor pressure of 4,393 mm Hg at 25 °C(3).
