  2. Chloralkali process - Wikipedia

    en.wikipedia.org/wiki/Chloralkali_process

    The chloralkali process (also chlor-alkali and chlor alkali) is an industrial process for the electrolysis of sodium chloride (NaCl) solutions. It is the technology used to produce chlorine and sodium hydroxide (caustic soda), [ 1 ] which are commodity chemicals required by industry.

  3. 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.

  4. 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.

  5. 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.

  6. Sodium hypochlorite - Wikipedia

    en.wikipedia.org/wiki/Sodium_hypochlorite

    Near the end of the nineteenth century, E. S. Smith patented the chloralkali process: a method of producing sodium hypochlorite involving the electrolysis of brine to produce sodium hydroxide and chlorine gas, which then mixed to form sodium hypochlorite. [35] [33] [36] The key reactions are: 2 Cl − → Cl 2 + 2 e − (at the anode)

  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]

  9. 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]
