一般的な説明
Chlorotrifluoroethylene is a colorless gas with a faint ethereal odor. Chlorotrifluoroethylene is shipped as a liquefied gas under its vapor pressure. Chlorotrifluoroethylene is very toxic by inhalation and is easily ignited. The vapors are heavier than air and a flame can flash back to the source of leak very easily. This leak can either be a liquid or vapor leak. The vapors can asphyxiate by the displacement of air. Contact with the liquid can cause frostbite. Under prolonged exposure to intense heat or fire the containers may violently rupture and rocket, or the material may polymerize with possible container rupture.
製法・合成法
製造方法
Chlorotrifluoroethylene is prepared from ethylene by the following route:Ethylene is treated with an excess of chlorine at 300-350C in the presence of activated charcoal to give hexachloroethane. This product is then treated with hydrogen fluoride in the presence of antimony pentachloride to yield trichlorotrifluoroethane. Dechlorination in the liquid phase with zinc dust and ethanol results in the formation of chlorotrifluoroethylene which is washed with water to remove alcohol, dried and distilled under pressure.
純化方法
Scrub it with 10% KOH solution, then 10% H2SO4 solution to remove inhibitors, dry and pass it through silica gel. It is stabilized with ~1% tributylamine. Use brass equipment. [Beilstein 1 III 646.] TOXIC GAS.
