Submitted April 12 2023 Revised May 10 2023 Accepted May 15 2023 Abstract The spontaneous oxidation of aqueous potassium manganate to aqueous potassium permanganate first carried out by the German alchemist of the 17th century Johann Rudolf Glauber was used for the manufacture of potassium permanganate until it was replaced with the electrolytic oxidation of potassium manganate which is the current state of the art. The reason for the replacement was that the method that is based on the Glauber reaction is commercially less efficient. In this minireview the efficiency of the Glauber reaction was evaluated by equilibrium determinations and comparatively viewed in light of today s principle of sustainability. The manufacture of potassium permanganate through the method based on the Glauber reaction is taking a step in the direction of building a more sustainable world. Keywords.
