• 解説

  クロロトリフルオロメタン．フレオン13ともいう．四塩化炭素を種々の触媒を用いてフッ化水素でフッ素化することにより得られる．常温でエーテル様の臭気のある無色の気体．融点－181 ℃，沸点－81.4 ℃．おもに電媒質の超低温用冷媒として用いられるが，環境法により生産が規制されている．

• 説明

  Strictly speaking, fluorocarbon compounds contain only the elements carbon, fluorine, and sometimes hydrogen. However, in industrial applications such as refrigerants and aerosol propellants, the term fluorocarbon has been used to include compounds containing chlorine and bromine atoms, or both. These industrial products have somewhat similar chemical and physical properties. Their relatively inert character and wide range of vapor pressures and boiling points make them especially well suited as refrigerants in a variety of applications, blowing agents for plastic foams, and aerosols.

• 化学的特性

  Colorless gas; ethereal odor. heavier than air. Nonflammable

• 使用

  Dielectric and aerospace chemical, hardening of metals, pharmaceutical processing.

• 一般的な説明

  CHLOROTRIFLUOROMETHANE is a colorless odorless gas. CHLOROTRIFLUOROMETHANE is shipped as a liquefied gas under its own vapor pressure. CHLOROTRIFLUOROMETHANE is noncombustible. CHLOROTRIFLUOROMETHANE can asphyxiate by the displacement of air. Contact with the liquid can cause frostbite. Exposure of the container to prolonged heat or fire may cause CHLOROTRIFLUOROMETHANE to rupture violently and rocket.

• 反応プロフィール

  The reaction of aluminum with various halogenated hydrocarbons produces a self-sustaining reaction with sufficient heat to melt aluminum pieces, examples of other halogenated hydrocarbons are fluorotrichloromethane, dichlorodifluoromethane, chlorodifluoromethane, tetrafluoromethane. The vigor of the reaction appears to be dependent on the combined degree of fluorination and the vapor pressure, [Chem. Eng. News 39(27):44(1961)].

• 危険性

  Toxic by inhalation; slightly irritant.

• 健康ハザード

  Exposure may cause nausea, dizziness, and headache, and rapid suffocation. Contact with skin may cause frostbite.

• 火災危険

  Special Hazards of Combustion Products: Toxic fumes of Cl and F

• 材料の用途

  The fluorocarbons are generally compatible with most of the common metals except at high temperatures. At elevated temperatures, the following metals resist fluorocarbon corrosion (and are named in decreasing order of their corrosive resistance): Inconel, stainless steel, nickel, steel, and bronze. Water or water vapor in fluorocarbon systems will corrode magnesium alloys or aluminum containing over 2 percent magnesium. These metals are not recommended for use with fluorocarbon systems in which water may be present.

• 安全性プロファイル

  A mild irritant. Narcotic in high concentrations. Reacts violently with Al. When heated to decomposition it emits highly toxic fumes of Fand Cl-.

• 貯蔵

  Use forced ventilation and local exhaust, or both, to prevent an accumulation of gas that could reduce the oxygen level to below 19.5%. Ensure good floor ventilation. Use a check valve or trap in the discharge line to prevent back flow into the cylinder. Where applicable, use a pressure-reducing regulator when connecting a cylinder to a low-pressure piping system. For flammable fluorocarbons, adherence to pertinent electrical standards is necessary. Personnel should not weld, solder, braze, or have an open flame of any type in atmospheres containing flammable or nonflammable fluorocarbons.

• 純化方法

  Main impurities are CO2, O2, and N2. The CO2 is removed by passage through saturated aqueous KOH, followed by conc H2SO4. The O2 is removed using a tower packed with activated copper on Kieselguhr at 200o, and the gas is dried over P2O5. [Miller & Smyth J Am Chem Soc 79 20 1957, Beilstein 1 III 42, 1 IV 34.] TOXIC GAS.
