  2. 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.

  3. 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.

  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 ).

  5. 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.

  6. Molten salt - Wikipedia

    en.wikipedia.org/wiki/Molten_salt

    Molten salt is salt which is solid at standard temperature and pressure but liquified due to elevated temperature. A salt that is liquid even at standard temperature and pressure is usually called a room-temperature ionic liquid , and molten salts are technically a class of ionic liquids.

  7. Electrolysis - Wikipedia

    en.wikipedia.org/wiki/Electrolysis

    Electrolysis of iron can eliminate direct emissions and further reduce emissions if the electricity is created from green energy. The small-scale electrolysis of iron has been successfully reported by dissolving it in molten oxide salts and using a platinum anode. [52] Oxygen anions form oxygen gas and electrons at the anode.

  8. 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. Castner process - Wikipedia

    en.wikipedia.org/wiki/Castner_process

    Diagram of Castner process apparatus. The Castner process is a process for manufacturing sodium metal by electrolysis of molten sodium hydroxide at approximately 330 °C. Below that temperature, the melt would solidify; above that temperature, the molten sodium would start to dissolve in the melt.
