• 解説

  メタン，エタンなど低級炭化水素の水素原子を，フッ素を主体とするハロゲン原子で置換した化合物の化学工業製品としての慣用名．最初，米国のdu Pont社で商品化され，Freon
  の名でよばれたが，同じ製品をわが国ではフロンという．多くの種類があって，フロンlmnのような番号で表示される．ここで，lは炭素原子数から1を引いた数，mは水素原子数に1を足した数，nはフッ素原子数，残りは塩素原子数を表す．たとえば，フロン113はC₂H₀F₃Cl₃である．用途として冷媒，エーロゾル噴霧剤，半導体製造プロセス(エッチング)用などがある．分解しにくいため成層圏にまで拡散し，成層圏のオゾン層を破壊する可能性が指摘されている．オゾン層の破壊は皮膚がんの増大や気候の変動をもたらす危険性がある．

• 用途

  製造用剤

• 化学的特性

  colourless liquid or gas

• 物理的性質

  Clear, colorless liquid with a carbon tetrachloride-like odor at high concentrations

• 使用

  Dry-cleaning solvent, fire extinguishers, to make chlorotrifluoroethylene, blowing agent, polymer intermediate, solvent drying, drying electronic parts and precision equipment.

• 一般的な説明

  Colorless liquid with a sweet, ether-like odor. Sinks in water.

• 空気と水の反応

  Insoluble in water.

• 反応プロフィール

  1,1,2-Trichlorotrifluoroethane yields violent reactions with Al, Ba, Li, Sm, Na/K alloy and Ti . May react exothermically with aluminum.

• 健康ハザード

  Inhalation causes irritation of the nose, throat, and lungs. High concentrations may cause death by respiratory failure or asphyxiation. May produce superficial skin burns or defatting type dermatitis and may irritate the eyes.

• 火災危険

  Noncombustible liquid.

• 工業用途

  1,1,2-Trichlorotrifluoroethane (CFC 113) is generally a stable molecule not prone to the reactivity that is often shown by the chlorinated hydrocarbons. The solvent blends that contain the fluorinated hydrocarbon and an alcohol display some metal reactivity which is inhibited by adding nitromethane as a stabilizer.

• 安全性プロファイル

  Mildly toxic by ingestion and inhalation. Affects the central nervous system in humans. A sktn irritant. Combustible when exposed to heat or flame. Incompatible with Al, Ba, Li, Sm, NaK alloy, Ti. See also CHLORINATED HYDROCARBONS, ALIPHATIC; and FLUORIDES.

• 職業ばく露

  TTE is used as a solvent and refrigerant; it is used in fire extinguishers; as a blowing agent and as an intermediate in the production of chlorotrifluoroethylene monomer by reaction with zinc.

• 発がん性

  A 2 year inhalation toxicity study/carcinogenicity study was conducted by Trochimowicz et al. in which groups of 100 male and 100 female rats were exposed to levels of up to of
  20,000 ppm of CFC 113 6 h/day, 5 days/week for 2 years. Although five nasal tumors were seen, one at 20,000 ppm and four at 10,000 ppm, all five were different morphological types and were judged not to be exposure related. In addition, there was a small increase (5.8%) in pancreatic islet cell adenomas in the females exposed to 20,000 ppm; however, this was within the normal control range.
  In a second study, injection of 0.1mLof 10% CFC 113 was not carcinogenic. But when given with a 5% solution of piperonyl butoxide, hepatomas were induced in male mice. The significance of this experimental finding has never been determined.

• 環境運命予測

  Biological. In an anoxic aquifer beneath a landfill in Ottawa, Ontario, Canada, there was evidence to suggest that 1,1,2-trichlorotrifluoroethane underwent reductive dehalogenation to give 1,2-difluoro-1,1,2-trichloroethylene and 1,2-dichloro-1,1,2-trifluoroethane. It was proposed that the latter compound was degraded via dehydrodehalogenation to give 1-chloro-1,1,2-trifluoroethylene (Lesage et al., 1990).
  Chemical/Physical. 1,1,2-Trichlorotrifluoroethane will not hydrolyze to any reasonable extent (Kollig, 1993).

• 輸送方法

  UN3082 Environmentally hazardous substances, liquid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

• 純化方法

  Wash it with water, then with weak alkali. Dry it with CaCl2 or H2SO4 and distil it. [Locke et al. J Am Chem Soc 56 1726 1934, Beilstein 1 III 157, 1 IV 142.]

• 不和合性

  Violent reaction with chemically active metals (such as powdered aluminum; beryllium, magnesium and zinc); calcium. Contact with alloys containing more than 2% magnesium causes decomposition, releasing hydrogen chloride, hydrogen fluoride; and carbon monoxide. May react exothermically with aluminum.

• 廃棄物の処理

  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.
