Wöhler process
Obsolete method of aluminum production / From Wikipedia, the free encyclopedia
The Wöhler process was one of the first routes for producing aluminium metal. It involves the reduction of anhydrous aluminium chloride with potassium, produced powdered aluminium:[1]
- AlCl3 + 3 K → Al + 3 KCl
With advent of more efficient means of electrolysis, e.g., Hall–Héroult process, the Wöhler process and related chemical-based routes became obsolete.
