Mn(III)OAc by electrolysis

What oxidizers can be used to oxidize manganese(II)acetate into mn(III)OAc ? can sodium percarbonate do this ? Im investigating an electrochemical and to make it work I use a devided carbon electrodes into acetic acid.

Here's an article from Erowid that completely explains the process. You are correct in that sodium percarbonate is your oxidizer.

The page you link to doesn't even contain the word 'percarbonate'. Oxidation of Mn(II) to Mn(III) can't be achieved by percarbonate anyway.

The oxidising agent in nearly all preparatory methods of Mn(OAc)<sub>3</sub> is KMnO<sub>4</sub>.

One day someone will use hypochlorite as oxidiser for this job but nothing reported so far that I know of.

Potassium permanganate... My bad.

But has anyone some other ideas ?

Pure Mn(III) compounds are hard to synthesise as it is. Most will prefer to make use of documented methods rather than try and reinvent the wheel.

Sodium Chlorite is also a strong oxidizer, is this usebel for the generation of Mn(III)OAc from standard Mn(III)OAc ? Still I need help with electrolytic oxidation of Mn(III)OAc, have anyone did this ever ? on Rhodium website als sayd it is possible to generate Mn(III)OAc from normal Mn(II)OAc.
