Abstract
The process for producing potassium permanganate, which comprises preparing a concentrated aqueous solution in potassium hydroxide of potassium manganate, diluting the solution with aqueous solution produced potassium hydroxide containing potassium manganate in a lower concentration, such being the concentration of potassium manganate in the solution resulting that the subsequent electrolytic oxidation produces an amount of potassium permanganate that is within its solubility in the solution after oxidation, electrolytically oxidizing the resulting solution to produce an aqueous solution of potassium hydroxide containing potassium permanganate in an increased concentration and potassium manganate in a decreased concentration and crystallize the highlight solution to produce crystals of potassium permanganate and mother liquor constituting said product solution.
