METHOD FOR STABILIZING ALKALINE SOLUTION OF HYDROGEN PEROXIDE Russian patent published in 2018 - IPC C01B15/37 

FIELD: chemistry.

SUBSTANCE: components in the following amounts (mole of substance/mole of hydrogen peroxide) are sequentially added to the aqueous hydrogen peroxide solution: magnesium sulfate (MgSO₄) - 0.0008÷0.0035; orthoboric acid (H₃BO₃) - 0.0008÷0.0035. Orthoboric acid is introduced into a solution of hydrogen peroxide after complete dissolution of magnesium sulfate. Alkali metal hydroxide is then introduced into the resulting solution in two portions at intervals of not less than 20 minutes.

EFFECT: increase in the stability time of the alkaline solution of hydrogen peroxide up to 1921 minutes with the use of smaller amounts of stabilizers, as well as decrease in the loss of active oxygen.
