MSDS Information

• Difluorochloromethane

クロロジフルオロメタン 化学特性,用途語,生産方法

• 用途

  エアコン、低温冷凍装置などの冷媒半導体エッチングガス、四フッ化樹脂原料、エアゾール噴射剤

• 化学的特性

  colourless gas

• 使用

  Refrigerant, low-temperature solvent, fluorocarbon resins, especially tetrafluoroethylene polymers.

• 一般的な説明

  Difluorochloromethane is a colorless gas with an ethereal odor. Difluorochloromethane is shipped as a liquefied gas under its own vapor pressure. Difluorochloromethane is noncombustible. Difluorochloromethane can asphyxiate by the displacement of air. Contact with the liquid can cause frostbite. Toxic gases can be produced in fires involving Difluorochloromethane. Exposure of the container to prolonged heat or fire may cause Difluorochloromethane to rupture violently and rocket.

• 空気と水の反応

  The liquefied gas poured into water can be violently explosive. This is due to the phase transition from superheated liquid to vapor.

• 反応プロフィール

  Difluorochloromethane is incompatible with the following: Alkalis, alkaline earth metals (e.g., powdered aluminum, sodium, potassium, zinc) .

• 危険性

  Asphyxiant. Central nervous system impairment, cardiac sensitization. Questionable carcinogen.

• 健康ハザード

  Inhalation at greater than 10% concentration in air may cause narcosis. Liquid may cause frostbite.

• 火災危険

  Special Hazards of Combustion Products: Decomposition gases are toxic and irritating.

• 安全性プロファイル

  Mddly toxic by inhalation. Experimental reproductive effects. Mutation data reported. An asphpant in hgh concentrations. At elevated pressures, 50% mixtures with air are combustible although ignition is dfficult. When heated to decomposition it emits toxic fumes of Fand Cl-. See also CHLORINATED HYDROCARBONS, ALIPHATIC; and FLUORIDES.

• 職業ばく露

  Chlorodifluoromethane is used as an aerosol propellant, refrigerant, and low-temperature solvent. It is used in the synthesis of polytetrafluoroethylene (PTFE).

• 発がん性

  In one study, an oral dose of 300mg of HCFC 22/kg of body weight was given to 36 male and 36 female rats 5 days/week for 52 weeks. The rats were held for 125 weeks compared to controls. There was no evidence of any treatment related increase in tumors. In an inhalation study 60 male and 60 female rats were exposed by inhalation to levels of
  5000 ppm of HCFC 22. The exposures were 4 h/day, 5 days/week for 104 weeks (rats) or 78 weeks (mice).

• 輸送方法

  UN1018 Chlorodifluoromethane, Hazard Class: 2.2; Labels: 2.2-Non-flammable compressed gas. Cylinders must be transported in a secure upright position, in a wellventilated 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

  The liquefied gas poured into water can be violently explosive. This is due to the phase transition from superheated liquid to vapor. Chlorodifluoromethane reacts violently with alkalies and alkaline earth metals; powdered aluminum; sodium, potassium, and zinc; causing fire and explosion hazard. Moisture and rust cause slow decomposition, forming toxic gases. Attacks some plastics, rubber, and coatings. Decomposes in heat forming fumes of chlorine, hydrogen chloride, HF, and phosgene. Attacks magnesium and its alloys.

• 廃棄物の処理

  Return refillable compressed gas cylinders to supplier. Return to vendor or send to licensed waste disposal company.
