Infobox references

Chlorotrifluoroethylene (CTFE) is a chlorofluorocarbon with chemical formula C F₂C Cl F. 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 has the trade name Neoflon PCTFE from Daikin Industries in Japan, and used to be produced under the trade name Kel-F from 3M Corporation in Minnesota.^[2]

Production

Chlorotrifluoroethylene is produced commercially by the dechlorination of 1,1,2-trichloro-1,2,2-trifluoroethane with zinc in methanol.

In 2012, an estimated 1-10 million pounds were produced commercially in the United States.
