Solid support stabilized Mn(III) and Mn(VII) and method of preparation

A method of producing stabilized Mn(VII), the method comprising the steps of:

• adding an H-saturated solid support material to Mn(II) in solution;
• raising the pH of the solution above about 12.0 to form Mn oxide, the Mn oxide being observable as a brown coloration in suspension;
• precipitating the Mn oxide from the solution onto the solid support material and drying the product to produce a supported Mn oxide material;
• reacting the supported Mn oxide material with phenylenediamine to form solid supported Mn(VII), the formation of the solid supported Mn(VII) being indicated by an observed violet color formation in the material so formed.

A method of producing Mn(II) from stabilized Mn(VII), the method comprising the steps of:

• adding a selected solid support material to Mn(II) in solution;
• precipitating Mn oxide from the solution onto the solid support material as Mn solid supported material and drying the resulting product;
• reacting the supported Mn product with an amine to form solid supported Mn(VII), the amine having the general formula R(NH2)n, representing a mono- or multi-amine-substituting organic compound where n≧ 1, and R=an alkyl or arylorganic moiety;
• and thereafter
• bubbling ozone or H2O2 into a solution containing the solid supported Mn(VII) to thereby form Mn(II).

A method of producing stabilized Mn oxide, the method comprising the steps of:

• adding a selected solid support material to Mn(II) in solution;
• precipitating Mn oxide from the solution onto the solid support material and drying the resulting product to produce a supported Mn oxide material;
• and
• wherein an H-saturated solid support material is added to Mn(II) in solution and precipitated to form supported Mn oxide material, followed by increasing or decreasing the pH of the solution by the addition or a suitable acid or base, respectively;
• and
• thereafter reacting the Mn oxide material with a selected one of 1,2-PDA, 1,4-PDA, HCl and 1,4-PDA , to thereby form a selected one of the Mn(II), Mn(III) or Mn(VII) oxide states or mixed Mn oxidation states.
