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 ...
tetrafluoroethylene-perfluoro-3,6-dioxa-4-methyl-7-octenesulfonic acid copolymer The molecular weight of Nafion is variable due to differences in processing and solution morphology. [ 3 ] [ 4 ] The structure of a Nafion unit illustrates the variability of the material; for example, the most basic monomer contains chain variation between the ...
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]
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).
While working with tetrafluoroethylene gas to develop refrigerants, he noticed that a previously pressurized cylinder had no pressure remaining. In dissecting the cylinder, he found a mass of white solid in a quantity similar to that of the tetrafluoroethylene gas. It was determined that this material was a new-to-the-world polymer. Tests ...
Hexafluoropropylene can be produced by pyrolysis of tetrafluoroethylene: [1] [2] 3 CF 2 =CF 2 → 2 CF 3 CF=CF 2. It can also be prepared from chlorodifluoromethane, or produced from various chlorofluorocarbons. [3]
Although highly reactive, difluorocarbene is an intermediate in the production of tetrafluoroethylene, ... In ordinary carbene, no π-MO-system is present, so the two ...
