Industrially, KMnO4 is produced by a two-part process. First, MnO2 is heated with KOH,
fusing it to form KMnO3, or potassium manganate. This is then subjected to acidic oxidation with hydrochloric acid to produce the permanganate. To produce the manganate, the DRY powders of KOH and MnO2 are merely homogeneously mixed, and heated. There will be a color change upon reaction. I have a reference for this, and I will get back to you with a quote and source w/in 12hrs. (going to work)
In this process for producing the triacetate, we first react the permanganate with hydrochloric acid further to yield MnCl2. This is then precipitated as the carbonate via addition of Na2CO3, which is then reacted with GAA to yield the acetate. Well, just oxidize your managanate straight to the MnCl2 state.
So, in conclusion:
KOH + MnO2
__> KMnO3
KMnO3 + HCl
__> KMnO4
__> MnCl2
MnCl2 + Na2CO3
__> MnCO3
MnCO3 + CH3COOH
__> Mn Triacetate,
Nifty, ain't it?
