Oxygen-carbon tetrafluoride reactions

Tetrafluoroethylene undergoes addition reactions typical of an olefin. It bums in air to form carbon tetrafluoride, carbonyl fluoride, and carbon dioxide (24). Under controlled conditions, oxygenation produces an epoxide (25) or an explosive polymeric peroxide (24). Trifluorovinyl ethers,... 

TEE (molecular weight 100.02) is a colorless, tasteless, odorless nontoxic gas [11]. It is stored as a liquid (its vapor pressure at -20°C is 1 MPa) and polymerized usually above its critical temperature of 33.3°C (91.9°E) and below its critical pressure 3.94 MPa (571 psi). The polymerization reaction is exothermic. In the absence of air it disproportionates violently to yield carbon and carbon tetrafluoride. This reaction generates the same amount of energy as an explosion of black powder. The decomposition is initiated thermally therefore, the equipment used in handling and polymerization of TFE has to be without hot spots. The flammability limits are 14% to 43% TFE burns when mixed with air and forms explosive mixtures with air and oxygen. The ignition temperature is 600°C to 800°C (1112°F to 1472°F) [12]. When stored in a steel cylinder it has to be under controlled conditions and with a suit-... 

Oxygen dilluoride reacts rapidly with selected alkenes at low temperatures 40 however, per-fluoroalkenes are less reactive than the corresponding alkylalkenes and require either thermal or ultraviolet activation.41 The oxidation, which is a homogeneous chain reaction,42 of hexa-fluoropropene, tetrafluorocyclopropene, and perfluorobut-2-ene all give a variety of products such as carbon tetrafluoride. carbonyl difluoride, hexafluoroethane, oxiranes, and other oxidation products.41 This reaction is not useful for preparative organic work.
