Halogenated Organic Compounds

Halogenated aliphatic compounds, such as HEXAFLUOROPROPYLENE, are moderately or very reactive. Halogenated organics generally become less reactive as more of their hydrogen atoms are replaced with halogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. Above a minimum oxygen pressure, the reaction of oxygen difluoride and hexafluoropropene to yield the hexafluoropropylene oxide becomes explosive, Chem. Abs., 1987, 107, 175302. The reaction of hexafluoropropene with grignard reagent (subst. phenylmagnesium bromides) led to explosion, Fluorine Chem., 1981, 18, 25.

Excerpt from ERG Guide 126 [Gases - Compressed or Liquefied (Including Refrigerant Gases)]: Use extinguishing agent suitable for type of surrounding fire. SMALL FIRE: Dry chemical or CO2. LARGE FIRE: Water spray, fog or regular foam. Move containers from fire area if you can do it without risk. Damaged cylinders should be handled only by specialists. FIRE INVOLVING TANKS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Do not direct water at source of leak or safety devices; icing may occur. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. Some of these materials, if spilled, may evaporate leaving a flammable residue. (ERG, 2016)

Excerpt from ERG Guide 126 [Gases - Compressed or Liquefied (Including Refrigerant Gases)]: As an immediate precautionary measure, isolate spill or leak area for at least 100 meters (330 feet) in all directions. LARGE SPILL: Consider initial downwind evacuation for at least 500 meters (1/3 mile). FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

Excerpt from ERG Guide 126 [Gases - Compressed or Liquefied (Including Refrigerant Gases)]: Do not touch or walk through spilled material. Stop leak if you can do it without risk. Do not direct water at spill or source of leak. Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material. If possible, turn leaking containers so that gas escapes rather than liquid. Prevent entry into waterways, sewers, basements or confined areas. Allow substance to evaporate. Ventilate the area.

Hexafluoropropene was identified, not quantified, in the stack emissions of a hazardous waste incinerator(1).

Hexafluoropropene's production and use in the manufacture of copolymers and hexafluoropropylene oxide(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 470(SRC), determined from a structure estimation method(2), indicates that hexafluoropropene is expected to have moderate mobility in soil(SRC). Volatilization of hexafluoropropene is expected from moist soil surfaces(SRC) given an estimated Henry's Law constant of 5.34 atm-cu m/mole(SRC), developed using a fragment constant estimation method(3). Hexafluoropropene is expected to rapidly volatilize from dry soil surfaces based on a vapor pressure of 4.9X10+3 mm Hg(SRC), determined from a fragment constant method(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 470(SRC), determined from a structure estimation method(2), indicates that hexafluoropropene is expected to adsorb to suspended solids and sediment in water(SRC). Hexafluoropropene is expected to volatilize rapidly from water surfaces(3,SRC) based on an estimated Henry's Law constant of 5.34 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Estimated half-lives for a model river and model lake are 4 and 116 hours, respectively(3,SRC). According to a classification scheme(5), an estimated BCF value of 24(3,SRC), from an estimated log Kow of 2.12(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), hexafluoropropene, which has a vapor pressure of 4.9X10+3 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase hexafluoropropene 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 21(3,SRC) and 95(4,SRC) days, respectively.

The rate constant for the vapor-phase reaction of hexafluoropropene with photochemically-produced hydroxyl radicals has been estimated as 7.74X10-13 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1,SRC). This corresponds to an atmospheric half-life of about 21 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1,SRC). The rate constant for the vapor-phase reaction of hexafluoropropene with ozone has been measured as 7.7X10-20 cu cm/molecule-sec at 25 °C(2). This corresponds to an atmospheric half-life of about 95 days at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(2,SRC). Hexafluoropropene is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(SRC).

An estimated BCF value of 24 was calculated for hexafluoropropene(SRC), using an estimated log Kow of 2.12(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 hexafluoropropene can be estimated to be about 470(SRC). According to a recommended classification scheme(2), this estimated Koc value suggests that hexafluoropropene is expected to have moderate mobility in soil(SRC).

The Henry's Law constant for hexafluoropropene is estimated as 5.34 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This value indicates that hexafluoropropene 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 4 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 116 hours(2,SRC). Hexafluoropropene's Henry's Law constant(1,SRC) indicates that volatilization from moist soil surfaces is expected(SRC). Hexafluoropropene is expected to volatilize rapidly from dry soil surfaces based on a vapor pressure of 4.9X10+3 mm Hg at 25 °C(3).

Occupational exposure may be through inhalation and dermal contact with this compound at workplaces where hexafluoropropene is produced or used. (SRC)
