[Chemical Properties]
Carbonyl fluoride is colorless or light yellow,
hygroscopic, compressed liquefied gas. Pungent, highly
irritating and suffocating odor. |
[General Description]
A colorless gas with a pungent odor. Very toxic by inhalation. Prolonged exposure of the containers to fire or heat may result in violent rupturing and rocketing. |
[Air & Water Reactions]
Reacts with water or steam to produces corrosive and toxic hydrofluoric acid fumes. |
[Reactivity Profile]
CARBONYL FLUORIDE is an acid fluoride. Incompatible with water, with bases (including amines), with strong oxidizing agents, with alcohols. Reacts violently with hexafluoroisopropylideneaminolithium. High temperature causes decomposition to toxic carbon monoxide gas and fluorine. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291]. |
[Health Hazard]
Irritates lungs, causing delayed pulmonary edema. Slight gassing produces dryness or burning sensation in the throat, numbness, pain in the chest, bronchitis, and shortness of breath. |
[Fire Hazard]
Special Hazards of Combustion Products: Toxic gas is generated when heated. |
[Hazard]
Toxic by inhalation, strong irritant to skin.
Lower respiratory tract irritant. Bone damage.
|
[Potential Exposure]
Carbonyl fluoride is a carboxy halide.
The major source of exposure to COF2 results from the
thermal decomposition of fluoro carbon plastics, such as
PTFE in air. Carbonyl fluoride is used for synthesizing
fluoroalkanes, difluoroisocyanates, and fluorinated alkyl
isocyanates. It may have been used as a military poison
gas. |
[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.
Medical observation is recommended for 24 to 48 hours after
breathing overexposure, as pulmonary edema may be delayed.
As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation
therapy. 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]
UN2417 Carbonyl fluoride, Hazard class: 2.3;
Labels: 2.3-Poisonous gas, 8-Corrosive material, Inhalation
Hazard Zone B. Cylinders must be transported in a secure
upright position, in a well-ventilated truck. Protect cylinder
and labels from physical damage. The owner of the compressed gas cylinder is the only entity allowed by federal
law (49CFR) to transport and refill them. It is a violation
of transportation regulations to refill compressed gas cylinders without the express written permission of the owner. |
[Incompatibilities]
Reacts with water to form toxic and corrosive HF gas. HF gas is highly reactive and forms explosive hydrogen gas on contact with metals. Do not use cast
iron or malleable fittings with carbonyl fluoride. Carbonyl
fluoride decomposes on heating above 450C producing
toxic gases, including HF. Not compatible with
hexafluoroisopropylidene-amino lithium; reaction may be
dangerous. |
[Description]
Carbonyl fluoride is a carboxy halide. It is colorless or light yellow, hygroscopic, compressed liquefiedgas, with a pungent, highly irritating and suffocating odor.Molecular weight=66.01; Specific gravity (H2O:1)=1.39at 2190℃; Boiling point=283℃; Freezing/Meltingpoint=2114℃; Relative vapor density (air=1)=2.29;Vapor pressure=55.4 atm. Hazard Identification (based onNFPA-704 M Rating System): Health 4, Flammability 0,Reactivity . Reacts with water. |
[Waste Disposal]
Return refillable compressed
gas cylinders to supplier. |
[Physical properties]
Colorless gas; pungent odor; hygroscopic; unstable; liquid density 1.139 g/mL (at -114°C); liquefies at -83.1°C; solidifies at -114°C; decomposes in water. |
[Preparation]
Carbonyl fluoride is prepared by the reaction of carbon monoxide with fluorine gas or silver fluoride:
CO + F2 → COF2
Also, it may be produced by the action of carbon monoxide with bromine trifluoride, BrF3. |
[storage]
