| | 1,1,2-Trichlorotrifluoroethane Usage And Synthesis |
| Chemical Properties | TTE is a colorless liquid. Carbon
tetrachloride-like odor at high concentrations. A gas above
48℃. | | Chemical Properties | colourless liquid or gas | | Physical properties | Clear, colorless liquid with a carbon tetrachloride-like odor at high concentrations | | Uses | Solvent for cleaning electronic equipment
and degreasing of machinery; refrigerant;
dry cleaning agent. | | Uses | 1,1,2-Trichloro-1,2,2-trifluoroethane is usedas a refrigerant and as a drycleaning solvent.It is also used as an extraction solvent foranalyzing petroleum hydrocarbons, oils, andgreases. | | Uses | Dry-cleaning solvent, fire extinguishers, to
make chlorotrifluoroethylene, blowing agent, polymer
intermediate, solvent drying, drying electronic
parts and precision equipment. | | Definition | ChEBI: 1,1,2-Trichlorotrifluoroethane is a chlorofluorocarbon and a haloalkane. It has a role as a refrigerant. | | General Description | Colorless liquid with a sweet, ether-like odor. Sinks in water. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | 1,1,2-Trichlorotrifluoroethane yields violent reactions with Al, Ba, Li, Sm, Na/K alloy and Ti . May react exothermically with aluminum. | | Health Hazard | Inhalation causes irritation of the nose, throat, and lungs. High concentrations may cause death by respiratory failure or asphyxiation. May produce superficial skin burns or defatting type dermatitis and may irritate the eyes. | | Health Hazard | The acute oral toxicity of this compoundis very low. The oral LD50 value in ratsis 43,000 mg/kg. The inhalation toxicity isalso low. Exposure to high concentrationscan produce a weak narcotic effect, car diac sensitization, and irritation of respi ratory passage. Chronic exposure causedliver enlargement in rats. A 6-hour expo sure to 87,000 ppm of 1,1,2-trichloro-1,2,2-trifluoroethane was lethal to rats. Ingestionof the liquid may cause nausea, lethargy,nervousness, and tremor. The irritant actionof the liquid was mild on rabbits’ skin. | | Fire Hazard | Noncombustible liquid. | | Industrial uses | 1,1,2-Trichlorotrifluoroethane (CFC 113) is generally a stable molecule not prone to the reactivity that is often shown by the chlorinated hydrocarbons. The solvent blends that contain the fluorinated hydrocarbon and an alcohol display some metal reactivity which is inhibited by adding nitromethane as a stabilizer. | | Safety Profile | Mildly toxic by
ingestion and inhalation. Affects the central
nervous system in humans. A sktn irritant.
Combustible when exposed to heat or
flame. Incompatible with Al, Ba, Li, Sm,
NaK alloy, Ti. See also CHLORINATED
HYDROCARBONS, ALIPHATIC; and
FLUORIDES. | | Potential Exposure | TTE is used as a solvent and refrigerant;
it is used in fire extinguishers; as a blowing agent and
as an intermediate in the production of chlorotrifluoroethylene
monomer by reaction with zinc. | | Carcinogenicity | A 2 year inhalation toxicity
study/carcinogenicity study was conducted by Trochimowicz
et al. in which groups of 100 male and 100 female
rats were exposed to levels of up to of 20,000 ppm of CFC
113 6 h/day, 5 days/week for 2 years. Although five nasal
tumors were seen, one at 20,000 ppm and four at 10,000 ppm,
all five were different morphological types and were judged
not to be exposure related. In addition, there was a small
increase (5.8%) in pancreatic islet cell adenomas in the
females exposed to 20,000 ppm; however, this was within
the normal control range.
In a second study, injection of 0.1mLof 10% CFC 113 was
not carcinogenic. But when given with a 5% solution of
piperonyl butoxide, hepatomas were induced in male
mice. The significance of this experimental finding
has never been determined. | | Environmental fate | Biological. In an anoxic aquifer beneath a landfill in Ottawa, Ontario, Canada, there was
evidence to suggest that 1,1,2-trichlorotrifluoroethane underwent reductive dehalogenation to give
1,2-difluoro-1,1,2-trichloroethylene and 1,2-dichloro-1,1,2-trifluoroethane. It was proposed that
the latter compound was degraded via dehydrodehalogenation to give 1-chloro-1,1,2-trifluoroethylene
(Lesage et al., 1990).
Chemical/Physical. 1,1,2-Trichlorotrifluoroethane will not hydrolyze to any reasonable extent
(Kollig, 1993). | | Shipping | UN3082 Environmentally hazardous substances,
liquid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous
material, Technical Name Required. | | Purification Methods | Wash it with water, then with weak alkali. Dry it with CaCl2 or H2SO4 and distil it. [Locke et al. J Am Chem Soc 56 1726 1934, Beilstein 1 III 157, 1 IV 142.] | | Incompatibilities | Violent reaction with chemically active
metals (such as powdered aluminum; beryllium, magnesium
and zinc); calcium. Contact with alloys containing
more than 2% magnesium causes decomposition, releasing
hydrogen chloride, hydrogen fluoride; and carbon monoxide.
May react exothermically with aluminum. | | Waste Disposal | Incineration, preferably after
mixing with another combustible fuel. Care must be exercised
to assure complete combustion to prevent the formation
of phosgene. An acid scrubber is necessary to remove
the halo acids produced. |
