Manganese Dioxide

Manganese dioxide is a mild and selective oxidant used for this purpose, although the reaction conditions may be critical to prevent over-oxidation. For example, short exposure of pyridoxol to activated manganese dioxide under acidic conditions affords pyridoxal in good yield whilst 4-pyridoxic acid is formed under basic conditions (Scheme 7) < 67JHC625 >.

US4089928A

An active natural manganese dioxide mineral for use in dry battery cells is produced from a natural manganese dioxide ore by reacting the ore or a preconcentrate thereof with a solution of an acid. The acid reacts with the carbonates, such as calcium carbonate, to produce water-soluble salts which are then washed away. The resultant mineral can have an MnO 2 content of 80% by weight or more.
