  2. Deacon process - Wikipedia

    en.wikipedia.org/wiki/Deacon_process

    The process was based on the oxidation of hydrogen chloride: 4 HCl + O 2 → 2 Cl 2 + 2H 2 O. The reaction takes place at about 400 to 450 °C in the presence of a variety of catalysts, including copper chloride (CuCl 2). Three companies developed commercial processes for producing chlorine based on the Deacon reaction: [1]

  3. Hydrogen chloride - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_chloride

    Flame inside HCl oven. Hydrogen chloride is produced by combining chlorine and hydrogen: Cl 2 + H 2 → 2 HCl. As the reaction is exothermic, the installation is called an HCl oven or HCl burner. The resulting hydrogen chloride gas is absorbed in deionized water, resulting in chemically pure hydrochloric acid. This reaction can give a very pure ...

  4. Mannheim process - Wikipedia

    en.wikipedia.org/wiki/Mannheim_process

    The Mannheim process is an industrial process for the production of hydrogen chloride and sodium sulfate from sulfuric acid and sodium chloride. [1] The Mannheim furnace is also used to produce potassium sulfate from potassium chloride. [2] The Mannheim process is a stage in the Leblanc process for the production of sodium carbonate.

  5. Leblanc process - Wikipedia

    en.wikipedia.org/wiki/Leblanc_process

    The hydrogen sulfide can be used as a sulfur source for the lead chamber process to produce the sulfuric acid used in the first step of the Leblanc process. Likewise, by 1874 the Deacon process was invented, oxidizing the hydrochloric acid over a copper catalyst: 4 HCl(g) + O_ 2 (g) → H 2 O(g) + Cl 2 (g)

  6. Chlorine production - Wikipedia

    en.wikipedia.org/wiki/Chlorine_production

    Potassium permanganate can be used to generate chlorine gas when concentrated hydrochloric acid is added to it: 2KMn04 + 16HCl —> 2KCl + 2MnCl2 + 8H2O + 5Cl2 This process has been investigated by Venable & Jackson and fails if the concentation of the hydrochloric acid solution drops below 2mM Venable, F. P.; Jackson, D.H. (1920). "The ...

  7. Aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Aqueous_solution

    In an aqueous solution the hydrogen ions (H +) and hydroxide ions (OH −) are in Arrhenius balance ([H +] [OH −] = K w = 1 x 10 −14 at 298 K). Acids and bases are aqueous solutions, as part of their Arrhenius definitions. [1] An example of an Arrhenius acid is hydrogen chloride (HCl) because of its dissociation of the hydrogen ion when ...

  8. Electrochlorination - Wikipedia

    en.wikipedia.org/wiki/Electrochlorination

    The solution travels to a tank that separates the hydrogen gas based on its low density. [1] Only water and sodium chloride are used. The simplified chemical reaction is: NaCl + H 2 O + energy → NaOCl + H 2 [citation needed] That is, energy is added to sodium chloride (table salt) in water, producing sodium hypochlorite and hydrogen gas.

  9. Photochlorination - Wikipedia

    en.wikipedia.org/wiki/Photochlorination

    In addition to chlorine, sulfur dioxide is also introduced into the reaction mixture. The products formed are alkylsulfonyl chlorides, which are further processed into surfactants. [28] Hydrochloric acid is formed as a coupling product, as is the case with photochlorination. Since direct sulfonation of the alkanes is hardly possible, this ...
