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 immedi ately with soap and water. Seek medical attention immedi ately. If this chemical has been inhaled, remove from
exposure, begin rescue breathing (using universal precau tions, 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. | [Shipping]

Trichlorofluoromethane is a chlorofluorocarbon (CFC) which is commonly used as a refrigerant, a foaming or blowing agent in industry, a solvent, an aerosol propellant, and in chemical syntheses.
Trichlorofluoromethane is a colorless, odorless gas at normal temperatures and pressures. Under high pressures as in cans, tanks or refrigerators it is in liquid form. When released from a pressurized container it evaporates almost instantly and can cause freezing at the point of release. At very high concentrations in air it may smell like ether. It is slightly soluble in water but evaporates quickly if exposed to air. The chemical formula for Trichlorofluoromethane is CFCL3. | [Chemical Properties]
Fluorotrichloromethane is a colorless liquid or
gas. Chlorinated solvent odor. The Odor Threshold is
5.0 ppm. | [Waste Disposal]
Incineration, preferably after
mixing with another combustible fuel. Care must be exer cised to assure complete combustion to prevent the forma tion of phosgene. An acid scrubber is necessary to remove
the halo acids produced. Consult with environmental regu latory agencies for guidance on acceptable disposal prac tices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform with EPA regulations govern ing storage, transportation, treatment, and waste disposal. | [Occurrence]
Trichlorofluoromethane is man-made and its presence in the environment is due to releases from common household and industrial uses. It is extremely stable in the atmosphere and does not degrade naturally. It can also be produced as an industrial by-product wherever chlorine products are used; including small quantities which are formed by reaction of chlorine disinfectants with organic pollutants in water. It is released into the air by leaking refrigeration units and air conditioners and by spray paint, spray varnish, spray cosmetics and other sprays in which it has been used as a propellant. Since 1978 many uses of trichlorofluoromethane as a propellant have been prohibited by law in the U.S. It can still be used as a propellant in some specialized products used in businesses and industries. It may also be found in air emissions and waste waters from a number of industries particularly refrigeration, electronics and foam manufacturing. | [Uses]
Aerosol propellant; refrigerant and
blowing agent; solvent for cleaning and
degreasing. | [Uses]
In refrigeration machinery requiring a refrigerant effective at negative pressures. As aerosol propellant. | [Uses]
Trichlorofluoromethane is a coolant in conditioning systems. It is a bulking agent for polymer foams. It is also used as a degrease solvent for printed circuit boards and to dry clean textiles. It is used as an aerosol propellant in various industries. | [Definition]
ChEBI: A one-carbon compound that is methane in which the hydrogens have been replaced by three chlorine and one fluorine atom. | [Chemical Reactivity]
Reactivity with Water: No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent. | [Carcinogenicity]
When administered by gavage
to groups of 50 male and 50 female mice at daily doses
of 1962 or 3952mg/kg, 5 days/week for 78 weeks followed
by a 13week observation period, there was no evidence of
carcinogenicity. Also,when given to rats at daily doses
of 488 and 977mg/kg for males and 538 and 1077mg/kg
for females, again for 5 days/week for 78 weeks, but followed
by a 28–33 week observation period, there was no
evidence of carcinogenicity. Maltoni et al. exposed
groups of 90 male and 90 female Sprague–Dawley rats
and groups of 60 male and 60 female Swiss mice by inhalation
to levels of 1000 and 5000 ppm 4 h/day, 5 days/week
for life. The exposures did not produce evidence of
carcinogenicity. | [Environmental Fate]
Biological. In a static-culture-flask screening test, trichlorofluoromethane was statically
incubated in the dark at 25 °C with yeast extract and settled domestic wastewater inoculum. No
significant degradation was observed after 28 d of incubation. At substrate concentrations of 5 and
10 mg/L, percent losses due to volatilization were 58 and 37% after 10 d (Tabak et al., 1981).
Chemical/Physical. When trichlorofluoromethane (50 μg/L) in an ultrasonicator was exposed to
20-kHz ultrasound at 5 °C, nearly 100% degradation was achieved after 6 min. During sonication,
the pH of the aqueous solution decreased, which is consistent with the formation of HCl,
hydrofluoric acid, and acidic species from fluorine and chlorine. In this experiment <5% of
trichlorofluoroethane was lost to volatilization (Cheung and Kurup, 1994). | [storage]
Color Code—Green: General storage may be used.Prior to working with this chemical you should be trainedon its proper handling and storage. Trichlorofluoromethanemust be stored to avoid contact with chemically activemetals, such as aluminum or lithium, since violent reactionsoccur. Store in tightly closed containers in a cool, well-ventilated area away from sources of heat. |
