트라이플루오로모노브로모메테인 C화학적 특성, 용도, 생산

화학적 성질

Trifluorobromomethane is a colorless gas with a slight ethereal odor. Shipped as a liquefied compressed gas.

용도

Used as fire extinguishing agent for oil, electrical equipment, organic solvent, natural gas and a variety of organics, especially for important military and civilian sites.

일반 설명

A colorless, odorless gas at room conditions Shipped as a liquid confined under its own vapor pressure. Noncombustible. Nontoxic but can asphyxiate by the displacement of air. Contact with the unconfined liquid can cause frostbite by evaporative cooling. Exposure of the container to prolonged heat or fire can cause BROMOTRIFLUOROMETHANE to rupture violently and rocket.

공기와 물의 반응

Slightly soluble in water.

반응 프로필

BROMOTRIFLUOROMETHANE may react with aluminum to produce substantial heat. Other halogenated hydrocarbons, such as fluorotrichloromethane, dichlorodifluoromethane, chlorodifluoromethane, tetrafluoromethane produce sufficient heat in this way to melt aluminum pieces. The vigor of the reaction appears to depend on the degree of fluorination and the vapor pressure [Chem. Eng. News 39(27):44 1961].

건강위험

Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating, corrosive and/or toxic gases.

화재위험

Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.

Safety Profile

Wildly toxic by inhalation. Incompatible with aluminum. When heated to decomposition it emits toxic fumes of Fand Br-. See also BROMIDES and FLUORIDES.

잠재적 노출

This material is used as a fire extinguishing agent, a chemical intermediate, and as a refrigerant.

운송 방법

UN1009 Bromotrifluoromethane or Refrigerant gas, R-13B, Hazard Class: 2.2; Labels: 2.2-Nonflammable gas. 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.

Purification Methods

Purify the gas by passing it through a tube containing P2O5 on glass wool into a vacuum system where it is frozen out in a quartz tube and degassed by a cycles of freezing, evacuating and thawing. [Beilstein 1 III 83, 1 IV 73.]

비 호환성

Keep away from chemically active metals, such as calcium, powdered aluminum; zinc, magnesium. Attacks some plastics, rubber, and coatings.

폐기물 처리

Return refillable compressed gas cylinders to supplier. 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.
