Sodium chloride (common salt) serves as a vital raw material for the production of numerous industrial chemicals. Through various chemical processes, it is transformed into essential substances:
- Chlorine and Sodium Hydroxide: These are produced simultaneously through the electrolytic decomposition of sodium chloride, a process known as the chlor-alkali industry.12
- Sodium Hypochlorite: Produced via the electrolysis of aqueous sodium chloride, this compound is widely used as a household and industrial bleach, as well as an antiseptic and fungicide.1
- Sodium Carbonate: Also known as soda ash, this is produced from sodium chloride using the Solvay process.1
- Sodium Sulfate: This can be manufactured synthetically by treating sodium chloride with sulfuric acid.1
- Metallic Sodium: This can be obtained through the electrolysis of fused (molten) sodium chloride.3
Additionally, the chlorine derived from sodium chloride is used as a precursor to manufacture a vast array of other chemicals, including hydrochloric acid, phosgene, and various organic compounds used in plastics, synthetic rubber, and antifreeze.3
