炭酸ジフルオリド 化学特性,用途語,生産方法

用途

合成中間体

化学的特性

Carbonyl fluoride is colorless or light yellow, hygroscopic, compressed liquefied gas. Pungent, highly irritating and suffocating odor.

物理的性質

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.

使用

Organic synthesis.

製造方法

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.

一般的な説明

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.

空気と水の反応

Reacts with water or steam to produces corrosive and toxic hydrofluoric acid fumes.

反応プロフィール

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].

危険性

Toxic by inhalation, strong irritant to skin. Lower respiratory tract irritant. Bone damage.

健康ハザード

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.

火災危険

Special Hazards of Combustion Products: Toxic gas is generated when heated.

安全性プロファイル

A poison. Moderately toxic by inhalation. A powerful irritant. Hydrolyzes instantly to form HF on contact with moisture. See also CARBONYLS, HYDROFLUORIC ACID, and FLUORINE. Incompatible with hexafluoroisoprop ylideneamino-lithium. When heated to decomposition it emits toxic fumes of CO and F-. See CARBON MONOXIDE for fire and explosion hazard.

職業ばく露

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.

輸送方法

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.

不和合性

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.

廃棄物の処理

Return refillable compressed gas cylinders to supplier.
