Tetrafluoroethylene is a reactive molecule that participates in myriad reactions. Owing to the presence of four fluorine substituents, its reactions differ strongly from the behavior of conventional alkenes such as ethylene. Tetrafluoroethylene dimerizes, giving octafluorocyclobutane. Even normal alkenes and dienes add tetrafluoroethylene in a ...
Ethylene tetrafluoroethylene (ETFE) is a fluorine-based plastic. It was designed to have high corrosion resistance and strength over a wide temperature range. ETFE is a polymer and its source-based name is poly (ethene-co-tetrafluoroethene). It is also known under the DuPont brand name Tefzel and is sometimes referred to as 'Teflon Film'. ETFE ...
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. [3] The commonly known brand name of PTFE-based composition is Teflon by Chemours, [4] a spin-off from DuPont, which originally invented the compound in 1938. [4]
A special but significant application of the fluorinated building block approach is the synthesis of tetrafluoroethylene, which is produced on a large-scale industrially via the intermediacy of difluorocarbene.
Only chloroform has significant applications of the haloforms. In the predominant application, chloroform is required for the production of tetrafluoroethylene (TFE), precursor to teflon. [1] Chloroform is fluorinated by reaction with hydrogen fluoride to produce chlorodifluoromethane (R-22).
Production [ edit ] In the radical telomerization of fluorotelomer molecules , a variety of fluorinated alkenes can serve as unsaturated taxogens including tetrafluoroethylene , vinylidene fluoride , chlorotrifluoroethylene , and hexafluoropropene .
A large-scale application of carbenes is the industrial production of tetrafluoroethylene, the precursor to Teflon. Tetrafluoroethylene is generated via the intermediacy of difluorocarbene: [22] CHClF 2 → CF 2 + HCl 2 CF 2 → F 2 C=CF 2
Fluorinated ethylene propylene (FEP) is a copolymer of hexafluoropropylene and tetrafluoroethylene.It differs from the polytetrafluoroethylene (PTFE) resins in that it is melt-processable using conventional injection molding and screw extrusion techniques. [2]
