    en.wikipedia.org/wiki/Fluorochemical_industry

    Laboratory setup for fluorine reactions, University of Freiburg. Fluorine gas may be stored in steel cylinders where the inside surface is passivated by a metal fluoride layer that resists further attack. [35] [4] Passivated steel will withstand fluorine provided the temperature is kept below 200 °C (392 °F). Above that temperature, nickel is ...

    The usefulness of fluorine-containing radiopharmaceuticals in 18 F-positron emission tomography has motivated the development of new methods for forming C–F bonds. Because of the short half-life of 18 F, these syntheses must be highly efficient, rapid, and easy. [25]

    A 2019 review argues that such 'concerted S N Ar' reactions are more prevalent than previously assumed. [3] Aryl halides cannot undergo the classic 'backside' S N 2 reaction. The carbon-halogen bond is in the plane of the ring because the carbon atom has a trigonal planar geometry. Backside attack is blocked and this reaction is therefore not ...

    Perfluoroalkanes are very stable because of the strength of the carbon–fluorine bond, one of the strongest in organic chemistry. [4] Its strength is a result of the electronegativity of fluorine imparting partial ionic character through partial charges on the carbon and fluorine atoms, which shorten and strengthen the bond (compared to carbon-hydrogen bonds) through favorable covalent ...

    Teflon story in particular is commonly included in popular histories of fluorine. Every element is different, but this one a lot of it's story is around compounds and the development of the fluorochemical industry. 71.127.137.171 ( talk ) 23:59, 1 November 2013 (UTC) [ reply ]

  9. Biological aspects of fluorine - Wikipedia

    PET scan using fluorine-18. Fluorine may interact with biological systems in the form of fluorine-containing compounds. Though elemental fluorine (F 2) is very rare in everyday life, fluorine-containing compounds such as fluorite occur naturally as minerals. Naturally occurring organofluorine compounds are extremely rare. Man-made fluoride ...
