Wöhler process

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: :AlCl 3 + 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.
