Chlorine is a greenish-yellow, diatonic gas that is a member of the halogen family of elements. It is toxic with corrosive properties that make it a powerful irritant that can cause pulmonary edema. Chlorine is widely used as bleach in the manufacture of paper and cloth and in the manufacture of solvents, pesticides, synthetic rubber, and refrigerants.
Chlorine is an element with the atomic symbol Cl, atomic number 17, and atomic weight 35. Its molecular formula is Cl2 and its CAS is 7782-50-5. Chlorine is used industrially as a reagent in synthetic chemistry, for water purification, and in the production of chlorinated lime, which is used in fabric bleaching. Chlorine is also a commonly used household cleaner and disinfectant as well as an oxidizing agent in water treatment and chemical processes. According to Burridge, E; Product Profile: Chlorine. European Chemical News, 82(2146): 35 (2005), Chlorine, like its co-product caustic soda, is produced by the electrolysis of brines using mercury, membrane, or diaphragm cells. Traditionally, electrolysis has been accomplished through the mercury amalgamor diaphragm cell processes. However, the ion exchange membrane cell is assuming a growing share due to environmental and economic considerations. Mercury cells are cheaper to operate than diaphragm cells when electricity costs are low, but mercury must be removed from the effluent. European producers are favoring the diaphragm cell method and have vowed to phase out the older mercury method by 2020.
