  2. Chlorine production - Wikipedia

    en.wikipedia.org/wiki/Chlorine_production

    The sodium–mercury amalgam flows to the center cell, where it reacts with water to produce sodium hydroxide and regenerate the mercury. Mercury cell electrolysis, also known as the Castner–Kellner process, was the first method used at the end of the nineteenth century to produce chlorine on an industrial scale.

  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. Oxychlorination - Wikipedia

    en.wikipedia.org/wiki/Oxychlorination

    In chemistry, oxychlorination is a process for generating the equivalent of chlorine gas (Cl 2) from hydrogen chloride and oxygen. [1] This process is attractive industrially because hydrogen chloride is less expensive than chlorine. [2]

  5. Castner–Kellner process - Wikipedia

    en.wikipedia.org/wiki/Castner–Kellner_process

    The first type, shown on the right and left of the diagram, uses an electrolyte of sodium chloride solution, a graphite anode (A), and a mercury cathode (M). The other type of cell, shown in the center of the diagram, uses an electrolyte of sodium hydroxide solution, a mercury anode (M), and an iron cathode (D). The mercury electrode is common ...

  6. Electrolysis of water - Wikipedia

    en.wikipedia.org/wiki/Electrolysis_of_water

    Using NaCl (salt) in an electrolyte solution yields chlorine gas rather than oxygen due to a competing half-reaction. Sodium bicarbonate (baking soda) instead yields hydrogen, and carbon dioxide for as long as the bicarbonate anion stays in solution. Match test used to detect the presence of hydrogen gas

  7. Mixed oxidant - Wikipedia

    en.wikipedia.org/wiki/Mixed_Oxidant

    A mixed oxidant solution (MOS) is a type of disinfectant that has many uses including disinfecting, sterilizing, and eliminating pathogenic microorganisms in water. [1] An MOS may have advantages such as a higher disinfecting power, stable residual chlorine in water, elimination of biofilm, and safety. [2]

  8. Liquefaction of gases - Wikipedia

    en.wikipedia.org/wiki/Liquefaction_of_gases

    Liquefied chlorine is transported for eventual solution in water, after which it is used for water purification, sanitation of industrial waste, sewage and swimming pools, bleaching of pulp and textiles and manufacture of carbon tetrachloride, glycol and numerous other organic compounds as well as phosgene gas.

  9. Industrial gas - Wikipedia

    en.wikipedia.org/wiki/Industrial_gas

    A gas regulator attached to a nitrogen cylinder. Industrial gases are the gaseous materials that are manufactured for use in industry.The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders.
