Patent ID: 7205049

Claim:
A process for producing a clear, colorless solution of a metal oxy peroxide of the formula MO(OOH) x where x is 2, 3, 4, or 6 comprising forming an aqueous solution of a metal peroxide having the formula M(OOH) y , where y is 2, 3, 4, or 6 where such solution is substantially free of other peroxides of the metal, diluting the solution to a metal peroxide concentration of between about 0.5% and about 0.85% by weight of the solution at a pH in the range of from about 4.0 to about 6.5, heating the solution to boiling for a period of from about 1 to about 4 hours, cooling the solution, reheating the solution to boiling for a period of between about 1 and about 2 hours, cooling the solution, reheating the solution to boiling until the peroxide concentration in the solution is in the range of from about 12.5% to about 25% by weight of the initially present metal peroxide, and cooling the resulting clear colorless solution.
