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.
Another earlier process to produce chlorine was to heat brine with acid and manganese dioxide. 2 NaCl + 2H 2 SO 4 + MnO 2 → Na 2 SO 4 + MnSO 4 + 2 H 2 O + Cl 2. Using this process, chemist Carl Wilhelm Scheele was the first to isolate chlorine in a laboratory. The manganese can be recovered by the Weldon process. [11]
It is the starting point for the chloralkali process, the industrial process to produce chlorine and sodium hydroxide, according to the chemical equation 2 NaCl + 2 H 2 O → e l e c t r o l y s i s Cl 2 + H 2 + 2 NaOH {\displaystyle {\ce {2 NaCl + 2 H2O ->[electrolysis] Cl2 + H2 + 2 NaOH}}}
The chlor-alkali industry is a major consumer of the world's energy budget. This process converts concentrated sodium chloride solutions into chlorine and sodium hydroxide, which are used to make many other materials and chemicals. The process involves two parallel reactions: 2 Cl − → Cl 2 + 2 e − 2 H 2 O + 2 e − → H 2 + 2 OH −
