Chlorotrifluoroethylene (CTFE) is a chlorofluorocarbon with chemical formula CFCl=CF 2. It is commonly used as a refrigerant in cryogenic applications. CTFE has a carbon-carbon double bond and so can be polymerized to form polychlorotrifluoroethylene or copolymerized to produce the plastic ECTFE .
PCTFE is a homopolymer of chlorotrifluoroethylene (CTFE), whereas PTFE is a homopolymer of tetrafluoroethylene. The monomers of the former differs from that of latter structurally by having a chlorine atom replacing one of the fluorine atoms.
Except where otherwise noted, data are given for materials in their standard state (at 25 °C ... Reduction of CFC-113 with zinc gives chlorotrifluoroethylene: [5]
ECTFE (ethylene-chlorotrifluoroethylene) is an alternating copolymer of ethylene and chlorotrifluoroethylene. It is a semi-crystalline fluoropolymer (a partly fluorinated polymer ), with chemical corrosion resistance properties.
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
The handling of this chemical may incur notable safety precautions. It is highly recommend that you seek the Material Safety Datasheet for this chemical from a reliable source such as eChemPortal, and follow its directions. Mallinckrodt Baker. FLUKA.
Bromotrifluoroethylene can be prepared from chlorotrifluoroethylene with high yields: [3] [4] F 2 C=ClF + HBr → CF 2 BrCHClF + Zn → CF 2 =CHF + ZnBrCl CF 2 =CHF + Br 2 → CF 2 BrCHBrF + KOH → CF 2 CHBr + KBr + H 2 O. It was first prepared by the Belgian chemist Frédéric Swarts in 1899. [5]
