Resorcinol Silicates Sodium Methylate Sodium Sulfate Products Solvents Sulfur Monochloride Chlorine is produced simultaneously with caustic soda, at a ratio of 1.0 to 1.1, usually through the electrolytic decomposition of salt solutions in electrolytic diaphragm, membrane or mercury cells. Chlorine is a critical chemical building block, the single material on which production of other chemicals most depends. Most pharmaceuticals and crop protection chemicals use chlorine in their production process, even if chlorine is not present in the final product. Chlorine also figures prominently in the production of many other organic compounds including solvents for metalworking, dry cleaning and electronics.
Chlorine is also widely used in drinking water purification and waste-water disinfection.
Its use has virtually eliminated the incidence of waterborne disease, such as cholera, dysentery and typhoid. All rights reserved.
