General Description
Colorless liquid with a sweet, ether-like odor. Sinks in water.
Reactivity Profile
1,1,2-TRICHLORO-1,2,2-TRIFLUOROETHANE(76-13-1) yields violent reactions with Al, Ba, Li, Sm, Na/K alloy and Ti . May react exothermically with aluminum.
Air & Water Reactions
Insoluble in water.
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.
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.
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical
attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit. If
frostbite has occurred, seek medical attention immediately;
do NOT rub the affected areas or flush them with water. In
order to prevent further tissue damage, do NOT attempt to
remove frozen clothing from frostbitten areas. If frostbite
has NOT occurred, immediately and thoroughly wash contaminated
skin with soap and water.
Shipping
UN3082 Environmentally hazardous substances,
liquid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous
material, Technical Name Required.
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.
Chemical Properties
colourless liquid or gas
Chemical Properties
TTE is a colorless liquid. Carbon
tetrachloride-like odor at high concentrations. A gas above
48℃.
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.
Physical properties
Clear, colorless liquid with a carbon tetrachloride-like odor at high concentrations
Definition
ChEBI: 1,1,2-Trichlorotrifluoroethane is a chlorofluorocarbon and a haloalkane. It has a role as a refrigerant.
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.
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).
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.]
