- General DescriptionChlorotrifluoroethylene 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.
- Air & Water ReactionsHighly flammable.
- Reactivity ProfileHalogenated aliphatic compounds, such as Chlorotrifluoroethylene, are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines; nitrides; azo/diazo compounds; alkali metals; strong oxidizers such as chlorine perchlorate, oxygen, bromine; and epoxides.
- HazardDangerous fire risk. Flammable limits in air 8.4–38.7%.
- Health HazardInhalation causes dizziness, nausea, vomiting; liver and kidney injury may develop after several hours and cause jaundice and necrosis of the kidney. Contact with liquid causes frostbite of eyes and possibly of skin.
- Safety ProfilePoison by ingestion and intraperitoneal routes. Moderately toxic by inhalation. Very dangerous fire hazard when exposed to heat, flames (sparks), or oxidizers. To fight fire, stop flow of gas. Violent reaction when mixed with (Brz + 02) or (CIF3 + water). Potentially explosive polymerization reaction with ethylene. Incompatible with 1,l -dchloroethylene; oxygen. When heated to decomposition it emits toxic fumes of Fand Cl-. See also CHLORINATED HYDROCARBONS, ALIPHATIC; and FLUORIDES.
- Purification MethodsScrub 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.
