Chlorotrifluoroethylene

Chinese name：三氟氯乙烯

CAS：79-38-9

EINECS：201-201-8

Molecular formula: C2ClF3

Molecular weight: 187.37

Density: 1.305 g/cm3

Melting point: −158 °C(lit.)

Boiling point: −28.4 °C(lit.)

Refractive index: 1.3800

Appearance : Colorless gas with ether odor, which decomposes in water and is easy to polymerize.

Purpose: The polymerization of chlorotrifluoroethylene into polychlorotrifluoroethylene has excellent electrical properties, heat resistance and chemical resistance, which is inferior to polytetrafluoroethylene, but it is easy to process. It can be made into plastics, films, coatings and other products, and the working temperature is - 196 ~ 199 ℃. It is also the raw material of fluoroplastics, fluororubber, refrigerant, fluorochlorine lubricating oil and halothane anesthetic. It is used to replace hydroxyl in steroids and carbohydrates with fluorine as preservative.

Properties

Trifluorochloroethylene is a colorless gas with a faint ethereal odor. It is shipped as a liquefied gas under its vapor pressure. It 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.
