An industrial electrochemical cell used to produce sodium metal and chlorine gas by electrolysis of molten sodium chloride (NaCl). The cell operates at high temperatures (around 600°C). It was designed by James C. Downs and is important for sodium metal production.
The Downs cell is the principal industrial process for manufacturing sodium metal, used in production of tetraethyllead (historical), sodium peroxide, sodium hydride, titanium (Kroll process uses Na), and pharmaceutical intermediates. Chlorine produced is used in PVC, bleach, and water treatment.
Molten sodium metal is extremely reactive with water, causing violent combustion and generation of caustic NaOH and H₂. The Downs cell operates at high temperature with highly reactive molten materials; industrial facilities require extensive safety engineering, containment systems, and trained oper…
