Reactivity ProfileThe reaction of aluminum with various halogenated hydrocarbons produces a self-sustaining reaction with sufficient heat to melt aluminum pieces, examples of other halogenated hydrocarbons are fluorotrichloromethane, dichlorodifluoromethane, chlorodifluoromethane, tetrafluoromethane. The vigor of the reaction appears to be dependent on the combined degree of fluorination and the vapor pressure, [Chem. Eng. News 39(27):44(1961)].
LuftstandardsThis action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Chlorotrifluoromethane is produced, as an intermediate or a final product, by process units covered under this subpart.
Chemical DangersDecomposes on burning. Decomposes on contact with hot surfaces. This produces toxic and corrosive fumes including hydrogen chloride, hydrogen fluoride and phosgene. Incompatible with certain metal powders (aluminium, zinc, beryllium), certain alloys (zinc, magnesium), certain plastics and natural rubber.

UmweltverhaltenTERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 188(SRC), determined from a measured log Kow of 1.65(2) and a recommended regression-derived equation(3), indicates that chlorotrifluoromethane is expected to have moderate mobility in soil(SRC). Volatilization of chlorotrifluoromethane is expected from moist soil surfaces(SRC) given a measured Henry's Law constant of 1.38 atm-cu m/mole(4). Chlorotrifluoromethane is expected to volatilize rapidly from dry soil surfaces based on a vapor pressure of 2.14X10+4 mm Hg(SRC) at 25 °C(5). Highly chlorinated/fluorinated compounds are not expected to biodegrade rapidly(6).AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 188(SRC), determined from a measured log Kow of 1.65(2) and a recommended regression-derived equation(3), indicates that chlorotrifluoromethane is not expected to adsorb to suspended solids and sediment in water(SRC). Chlorotrifluoromethane is expected to volatilize rapidly from water surfaces(3) based on a measured Henry's Law constant of 1.38 atm-cu m/mole(4). Estimated half-lives for a model river and model lake are 3 and 97 hours, respectively(SRC). According to a classification scheme(5), an estimated BCF value of 10(3,SRC), from the measured log Kow(2), suggests that bioconcentration in aquatic organisms is low(SRC). Highly chlorinated/fluorinated compounds are not expected to biodegrade rapidly(6).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), chlorotrifluoromethane, which has a measured vapor pressure of 2.14X10+4 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase chlorotrifluoromethane is slowly 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 62 years(3,SRC). This compound will gradually diffuse into the stratosphere above the ozone layer where it will slowly degrade due to direct photolysis from UV-C radiation and contribute to the catalytic removal of stratospheric ozone(4,SRC). The half-life for this reaction has been estimated to range from 180 to 450 years(4).

Soil Adsorption/MobilityThe Koc of chlorotrifluoromethane is estimated as approximately 188(SRC), using a measured log Kow of 1.65(1) and a regression-derived equation(2). According to a recommended classification scheme(3), this estimated Koc value suggests that chlorotrifluoromethane is expected to have moderate mobility in soil(SRC).
Atmospheric ConcentrationsChlorotrifluoromethane was detected in the troposphere above the Antarctic region at concentrations of 3.6 and 3.2 parts per trillion, with an average global concentration estimated as 4.0 parts per trillion(1). Chlorotrifluoromethane was detected at a concentrations of 3.9 parts per trillion (14.4 kilometers above the earth's surface) and 2.3 parts per trillion (33.2 kilometers above the earth's surface)(2).Trace gases have been measured, by electron-capture gas chromatography and gas chromatography-mass spectrometry, at the South Pole (SP) in Antarctica and in the US Pacific Northwest (PNW) (aprox 45 deg N) during Jan of each year 1975-80. The concn of chlorotrifluoromethane increased at a rate of 12%/yr at the SP and 8%/yr in the PNW.

Artificial Pollution SourcesChlorotrifluoromethane's production and use as a refrigerant or as an azeotrope with CHF3 for very low temperature applications(1) may lead to its release to the environment through various waste streams(SRC).
Environmental BiodegradationHighly chlorinated/fluorinated compounds are not expected to biodegrade rapidly(1).
Environmental BioconcentrationAn estimated BCF value of 10 was calculated for chlorotrifluoromethane(SRC), using a measured log Kow of 1.65(1) and a recommended regression-derived equation(2).
