  2. Chloralkali process - Wikipedia

    en.wikipedia.org/wiki/Chloralkali_process

    The net process is the electrolysis of an aqueous solution of NaCl into industrially useful products sodium hydroxide (NaOH) and chlorine gas. Saturated brine is passed into the first chamber of the cell.

  3. Downs cell - Wikipedia

    en.wikipedia.org/wiki/Downs_cell

    The Downs cell uses a carbon anode and an iron cathode.The electrolyte is sodium chloride that has been heated to the liquid state. Although solid sodium chloride is a poor conductor of electricity, when molten the sodium and chloride ions are mobilized, which become charge carriers and allow conduction of electric current.

  4. Castner–Kellner process - Wikipedia

    en.wikipedia.org/wiki/Castner–Kellner_process

    The Castner–Kellner process is a method of electrolysis on an aqueous alkali chloride solution (usually sodium chloride solution) to produce the corresponding alkali hydroxide, [1] invented by American Hamilton Castner and Austrian Carl Kellner in the 1890s.

    The net process is the electrolysis of an aqueous solution of NaCl into industrially useful products sodium hydroxide (NaOH) and chlorine gas. Electrofluorination

  6. Chlorine production - Wikipedia

    en.wikipedia.org/wiki/Chlorine_production

    Chlorine can be manufactured by the electrolysis of a sodium chloride solution , which is known as the Chloralkali process. The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H 2). These two products, as well as chlorine itself, are highly reactive.

  7. Electrochlorination - Wikipedia

    en.wikipedia.org/wiki/Electrochlorination

    A low voltage DC current is applied, electrolysis happens producing sodium hypochlorite and hydrogen gas (H 2). 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]

  8. Mixed oxidant - Wikipedia

    en.wikipedia.org/wiki/Mixed_Oxidant

    Operation principle of NaCl electrolysis cell. The basis of the mixed oxidant production cell is electrolysis of a water solution of sodium chloride. For producing a mixed oxidants solution, different types of electrolysis cells such as a membrane cell or a standard contact cell (both unipolar and bipolar) are used. [9]

  9. Sodium hypochlorite - Wikipedia

    en.wikipedia.org/wiki/Sodium_hypochlorite

    3 NaOCl(aq) → 2 NaCl(aq) + NaClO 3 (aq) This reaction is exploited in the industrial production of sodium chlorate. An alternative decomposition of hypochlorite produces oxygen instead: 2 OCl − → 2 Cl − + O 2. In hot sodium hypochlorite solutions, this reaction competes with chlorate formation, yielding sodium chloride and oxygen gas: [25]
