유해성 요약	In confined space spill, may displace air and act as simple asphyxiantEvaporating liquid can cause frostbiteAt high concentrations, may sensitize heart to arrhythmias[ICSC] May cause irritationMay cause rapid suffocation[MSDSonline] It has anesthetic effects at high concentrationsThreshold for cardiac sensitization in rats is 50,000 ppm[AIHA]The major hazards encountered in the use and handling of freon 142b stem from its toxicologic properties and flammability. Exposure to this colorless, nearly odorless gas may be occur to the general population through inhalation of freon 142b as a propellant in aerosol sprays, and to workers through inhalation or dermal contact during the manufacture, use, servicing, and disposal of refrigeration units, food processing, plastic foam blowing, and fire extinguishing, among others. Inhalation of freon 142b may cause dizziness and suffocation, while dermal contact may cause defatting of skin and frostbite. Sufficient exhaust and general ventilation should be provided to keep vapor concentration below recommended levels (a threshold limit of about 500 ppm for repeated workday exposure was suggested). Also, wear appropriate chemical protective gloves and goggles, and in emergency situations such as spills or fire fighting wear a positive pressure self-contained breathing apparatus and full protective clothing. Freon 142b is extremely flammable. Atmospheres of freon in the range of 6.2% to 17.9% in air can ignite explosively when contacted by heat, sparks, or flames. Freon 142b may travel to a source of ignition and flash back. Also, freon vapor, in confined spaces presents an explosion hazard. When leaking containers of freon (including tank cars, tank trucks, and storage tanks) are on fire, let them burn unless the flow can be stopped. From as far a distance as possible, use water spray to knock down vapor and to cool fire-exposed containers. To fight small freon 142b fires, use dry chemical or CO2, and for large fires use water spray, fog, or foam. For uncontrollable fires or the pssibility of container eruption, consider evacuation of 1/2 mile radius and the use of unmanned hose holders. When heated to decomposition, this substance emits toxic fumes of fluoride and chloride as well as small amounts of phosgene. Fire fighters should wear a self-contained breathing apparatus and full protective clothing. Store and use freon 142b cylinders in well ventilated areas away from heat, all ignition sources, and all highly oxidizing and flammable materials. Freon 142b should be in DOT-approved, low pressure cylinders, equipped with brass valves. Containers may be shipped via road, and water (forbidden on passenger and aircraft or railcar), and should be affixed with labels stating, "Flammable Gas". Before transporting freon 142b, the regulatory requirements of the DOT should be consulted. If freon 142b spills or leaks, shut off ignition sources (eg, no flares or smoking), stop leak if it can be done without risk (do not touch the material), and isolate the area. Water spray may be used to reduce the vapor, but care is needed to prevent the material from entering water sources or sewers. Consult with environmental regulatory agencies for guidance on acceptable disposal practices.

일반 설명

A colorless, odorless gas shipped as a liquid under own vapor pressure. Contact with the unconfined liquid may cause frostbite by evaporative cooling. Easily ignited. Vapors heavier than air. A leak may be either liquid or vapor. May asphyxiate by the displacement of air. Prolonged exposure to fire or intense heat may cause the containers to violently rupture and rocket.

제조 및 합성 방법

생산 방법

Chlorodifluoroethane is prepared by the chlorination of difluoroethane in the presence of a suitable catalyst; hydrochloric acid is also formed. The chlorodifluoroethane is purified to remove all traces of water and hydrochloric acid, as well as traces of the starting and intermediate materials.
