  2. Perchloryl fluoride - Wikipedia

    en.wikipedia.org/wiki/Perchloryl_fluoride

    Perchloryl fluoride is produced primarily by the fluorination of perchlorates. The initial syntheses in the early 1950s used fluorine gas or fluorides and anodic oxidation as the fluorinating agents, but these give explosive gaseous mixtures. [8] A common fluorinator in modern syntheses is antimony pentafluoride: [3]: 372–373 ClO − 4 + 3 HF ...

  3. Chloryl fluoride - Wikipedia

    en.wikipedia.org/wiki/Chloryl_fluoride

    ClO 2 F was first reported by Schmitz and Schumacher in 1942, who prepared it by the fluorination of ClO 2. [2] The compound is more conveniently prepared by reaction of sodium chlorate and chlorine trifluoride [3] and purified by vacuum fractionation, i.e. selectively condensing this species separately from other products. This species is a ...

  4. Substitution reaction - Wikipedia

    en.wikipedia.org/wiki/Substitution_reaction

    When chlorine gas (Cl 2) is irradiated, some of the molecules are split into two chlorine radicals (Cl•), whose free electrons are strongly nucleophilic. One of them breaks a C–H covalent bond in CH 4 and grabs the hydrogen atom to form the electrically neutral HCl.

  5. Fluorine compounds - Wikipedia

    en.wikipedia.org/wiki/Fluorine_compounds

    The well-characterized heavier halogens (chlorine, bromine, and iodine) all form mono-, tri-, and pentafluorides: XF, XF 3, and XF 5. Of the neutral +7 species, only iodine heptafluoride is known. [93] While chlorine and bromine heptafluorides are not known, the corresponding cations ClF + 6 and BrF + 6, extremely strong oxidizers, are. [94]

  6. Flow battery - Wikipedia

    en.wikipedia.org/wiki/Flow_battery

    A typical flow battery consists of two tanks of liquids which are pumped past a membrane held between two electrodes. [1]A flow battery, or redox flow battery (after reduction–oxidation), is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane.

  8. Halogenation - Wikipedia

    en.wikipedia.org/wiki/Halogenation

    Such reagents include cobalt trifluoride, chlorine trifluoride, and iodine pentafluoride. [4] The method electrochemical fluorination is used commercially for the production of perfluorinated compounds. It generates small amounts of elemental fluorine in situ from hydrogen fluoride. The method avoids the hazards of handling fluorine gas.
