2. Sodium hydroxide - Wikipedia

   en.wikipedia.org/wiki/Sodium_hydroxide

   Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...

3. 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.

4. 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.

5. Alkali manufacture - Wikipedia

   en.wikipedia.org/wiki/Alkali_manufacture

   The sodium sulfate is afterwards fired with calcium carbonate and coal. Sodium carbonate can be extracted from this mixture by washing the mixture with water. [2] Until the rise of the ammonia-soda process, which has better economics, the Leblanc process was used extensively making the United Kingdom the lead in alkali production. By the early ...

6. 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.

7. 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 ...
