Description
Colorless gas; faint ethereal odor. Decomposes in water.
Trifluorochloroethylene is a colorless gas with a faint ethereal odor. It is shipped as a liquefied gas under its vapor pressure. It is very toxic by inhalation and is easily ignited. The vapors are heavier than air and a flame can flash back to the source of leak very easily. This leak can either be a liquid or vapor leak. The vapors can asphyxiate by the displacement of air. Contact with the liquid can cause frostbite. Under prolonged exposure to intense heat or fire the containers may violently rupture and rocket, or the material may polymerize with possible container rupture.|GasVapor|COLOURLESS ODOURLESS GAS.

Halogenated Organic Compounds
Highly Flammable
Halogenated aliphatic compounds, such as TRIFLUOROCHLOROETHYLENE, are moderately or very reactive. Halogenated organics generally become less reactive as more of their hydrogen atoms are replaced with halogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines; nitrides; azo/diazo compounds; alkali metals; strong oxidizers such as chlorine perchlorate, oxygen, bromine; and epoxides.

For fires involving flammable gases, the best procedure is to stop the flow of the gas before attempting extinguishment of the fire. To extinguish the fire while allowing continued flow of the gas is extremely dangerous; an explosive cloud of gas/air mixture may be created that, if ignited, may cause far more damage than the original fire. Extinguishing the flame using carbon dioxide or dry chemical may be desirable to allow immediate access to valves to shut off the flow of gas, but this must be done carefully. In many cases, it will be preferable to allow continued burning, while protecting exposures with water spray, until the flow of gas can be stopped.|If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped.

The effect of isoflurane on the anaerobic metabolism of halothane to chlorodifluoroethene (CDE) and chlorotrifluoroethane (CTE) was studied with microsomes of guinea pig liver. The Km values for chlorotrifluoroethane formation were 1204.74, 553.75, 521.14, 560.67, and 711.05 uM at 0 mM, 0.12 mM, 0.29 mM, 0.58 mM and 1.16 mM isoflurane, respectively. In contrast, the Vmax values for chlorodifluoroethene and chlorotrifluoethane formation at these isoflurane concentrations were not significantly different than in the control groups. The production of chlorodifluoroethene and chlorotrifluoroethane was significantly increased by isoflurane, at concentrations up to 0.58 mM.

Chlorotrifluoroethylene's production and use as a chemical intermediate(1) may result in its release to the environment through various waste streams(SRC). The transformation of trichlorotriflurorethane (CFC-113) in the environment is believed to occur via reductive dechlorination to form 1,2-dichloro-1,2,2-trifluoroethane and then, through elimination, chlorotrifluoroethylene(2).|Chlorotrifluoroethylene was found to be a biodegradation product of trichlorotrifluoroethane in an investigation of natural attenuation potential of peat and sewage sludge from a Dutch halogen-contaminated industrial site(1). In groundwater studies of the Gloucester landfill project in Ontario, Canada, trichlorotrifluoroethylene is biotransformed via reductive dechlorination to form chlorotrifluoroethylene(2).
TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 95(SRC), determined from a structure estimation method(2), indicates that chlorotrifluoroethylene is expected to have high mobility in soil(SRC). Volatilization of chlorotrifluoroethylene from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 0.31 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Chlorotrifluoroethylene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 4.59X10+3 mm Hg at 25 °C(4). Biodegradation data in soil were not available(SRC,2010).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 95(SRC), determined from a structure estimation method(2), indicates that chlorotrifluoroethylene is not 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 0.31 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 3 hours and 4 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 6(SRC), from an estimated log Kow of 1.65(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Biodegradation data in water were not available(SRC, 2010).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), chlorotrifluoroethylene, which has a vapor pressure of 4.59X10+3 mm Hg at 25 °C(2), is expected to exist solely as a gas in the ambient atmosphere. Gas-phase chlorotrifluoroethylene 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 2.5 days(SRC), calculated from its rate constant of 7.0X10-12 cu cm/molecule-sec at 25 °C(3). The rate constant for the vapor-phase reaction of chlorotrifluoroethylene with ozone has been estimated as 0.002X10-17 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(4). This corresponds to an atmospheric half-life of about 720 days at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(5). The chlorine-atom initiated oxidation of chlorotrifluoroethylene in the atmosphere gives CClF2CF(O) as the major product; the quantum yield of oxidation for this reaction is >1000 relative to the quantum yield for olefin(6). A rate constant of 2.7X10-11 cm cu/mol sec is reported for the reaction of chlorotrifluoroethylene with atomic oxygen(7). Chlorotrifluoroethylene does not contain chromophores that absorb at wavelengths >290 nm(8), and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).
The rate constant for the vapor-phase reaction of chlorotrifluoroethylene with photochemically-produced hydroxyl radicals is 7.0X10-12 cu cm/molecule-sec at 25 °C(1). This corresponds to an atmospheric half-life of about 2.5 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(2). Chlorotrifluoroethylene is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). Chlorotrifluoroethylene 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).|The chlorine-atom initiated gas phase, room temperature oxidation of chlorotrifluoroethylene proceeds by a long chain free radical process(1) with the major product (95%) being CClF2CF(O)(2). The quantum yield of oxidation for this reaction is >1000 relative to the quantum yield for olefin(2). The ozonolysis of chlorotrifluoroethylene proceeds through chain oxidation, carried by a diradical mechanism which is inhibited in the presence of O2. The major product of the reaction is the corresponding carbonyl product(1). The rate constant for the vapor-phase reaction of chlorotrifluoroethylene with ozone has been estimated as 0.002X10-17 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). This corresponds to an atmospheric half-life of about 720 days at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(4). The primary product of this reaction is the corresponding carbonyl product(1). In the reaction of atomic oxygen with chlorotrifluoroethylene, CF2O and CFClO were reported as products with CF2O the more important; CFClO may have been a contaminant(1). A rate constant of 2.7X10-11 cm cu/mol sec is reported for the reaction of chlorotrifluoroethylene with atomic oxygen using flash photolysis and kinetic spectroscopy(5). Chlorotrifluoroethylene has a measured half-life of approximately 42 days in landfill leachate. It degrades in less than a day in sulfide-containing buffer(6).
An estimated BCF of 6 was calculated in fish for chlorotrifluoroethylene(SRC), using an estimated log Kow of 1.65(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Using a structure estimation method based on molecular connectivity indices(1), the Koc of chlorotrifluoroethylene can be estimated to be 95(SRC). According to a classification scheme(2), this estimated Koc value suggests that chlorotrifluoroethylene is expected to have high mobility in soil. Chlorotrifluoroethylene is believed to be more mobile than 1,1,2-trichloro-1,2,2-trifluoroethane (CFC-113) as it is less halogenated; CFC-113 has a retardation factor of approximately 10 in a sand and gravel aquifer with an organic carbon content of 0.06%(3).
The Henry's Law constant for chlorotrifluoroethylene is estimated as 0.31 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that chlorotrifluoroethylene 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 3 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 4 days(SRC). Chlorotrifluoroethylene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Chlorotrifluoroethylene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 4.59X10+3 mm Hg(3).
According to the 2006 TSCA Inventory Update Report, the number of persons reasonably likely to be exposed in the industrial manufacturing, processing, and use for chlorotrifluoroethylene is 100-999; the data may be greatly underestimated(1).|Occupational exposure to chlorotrifluoroethylene may occur through inhalation and dermal contact with this compound at workplaces where chlorotrifluoroethylene is produced or used.

After exposure of rabbits to trifluorochloroethylene at 0.1%, the alveolar absorption rate was 5.80%. Trifluorochloroethylene was detected in blood and urine. The kidney, bone, and lung had the highest distribution among various organs examined.
Two metabolites of CTFE were identified as potent nephrotoxins in male rats, S-(2-chloro-1,1,2-trifluoroethyl)glutathione (CTFG) and S-(2-chloro-1,1,2-trifluoroethyl)cysteine (CTFC). In this investigation both CTFG and CTFC were synthesized and given to the male rats at dose levels of 50 umol/kg of CTFG or 100 umol of CTFC. It was concluded that the metabolites of CTFE are the active nephrotoxins, not CTFE.|This study describes in vivo bioactivation of CTFE which proceeds as follows: hepatic glutathione S-conjugate formation, peptidase-catalyzed metabolism of the glutathione S-conjugates to the corresponding cysteine S-conjugates, uptake of cysteine S-conjugates by the kidneys, and renal cysteine conjugate beta-lyase-catalyzed beta-elimination of a thiol. The CTFE conjugate was shown to be capable of acylating renal proteins using (19)F NMR.|Since halogenated vinyl cysteine conjugates are known to be potent nephrotoxicants, chlorotrifluoroethylene was studied for its ability to be metabolically activated to the cysteine conjugate. This was shown not to occur in a biological system. However, if a glutathione adduct of chlorotrifluoroethylene is synthesized, this adduct was shown to degrade non-enzymatically to form the cysteine conjugate. Thus, incubation of chlorotrifluoroethylene with a renal cortex brush border preparation high in C-S lyase did not result in the formation of pyruvate, indicating the lack of ability of a renal preparation to directly activate chlorotrifluoroethylene presumably because of the inability to form the glutathione adduct.|Chlorotrifluoroethylene, a substrate for glutathione S-transferase activity in rat hepatic cytosolic and microsomal fractions, was investigated, wherein the rates of reaction were determined by measuring glutathione disappearance, at 5-15 or 35-70 nmol/min/mg of cytosolic or microsomal protein, respectively. A product of the cytosol-catalyzed reaction between chlorotrifluoroethylene and glutathione was S-(2-chloro-1,1,2-trifluoroethyl)glutathione. The glutathione S-transferase-catalyzed addition reaction with a halogenated olefin may be of toxicological significance.|For more Metabolism/Metabolites (Complete) data for Chlorotrifluoroethylene (9 total), please visit the HSDB record page.

Chlorotrifluoroethylene Use and Manufacturing
Germany first produced chlorotrifluoroethylene in 1934, and the United States realized industrial production in 1949. The method commonly used in industry is the dechlorination of trifluorotrichloroethane. Generally, zinc powder is used as a dechlorination agent, methanol is used as a solvent, the reaction temperature is 50-150°C, the reaction pressure is 2.08MPa, and the reaction time is 3-4s. The methanol suspension containing zinc powder and trifluorotrichloroethane are fed into the reactor together, and the zinc chloride produced is separated from the reactants, and the reaction products are sent to the initial distillation tower and the rectification tower to obtain pure trifluoride Vinyl chloride. Raw material consumption quota: trifluorotrichloroethane 1830kg/t, methanol (>95%) 1080kg/t, zinc powder (>95%) 840kg/t.
Polymerization of chlorotrifluoroethylene into polychlorotrifluoroethylene has excellent electrical properties, heat resistance and chemical resistance inferior to polytetrafluoroethylene, but it is easy to process and can be made into plastics, films, paints and other products, and the working temperature is- 196~199℃. It is also the raw material of fluoroplastics, fluororubbers, refrigerants, fluorochloro lubricants, halothane anesthetics. Used to replace hydroxy groups in steroids and carbohydrates with fluorine as a preservative.
