METHOD OF STABILISING HYDROGEN PEROXIDE ALKALINE SOLUTION Russian patent published in 2013 - IPC C01B15/37 

FIELD: chemistry.

SUBSTANCE: invention relates to method of stabilising hydrogen peroxide alkaline solution, applied for synthesis of peroxide compounds of alkaline metals or their composite mixtures. Method of stabilising hydrogen peroxide alkaline solution consists in sequential addition of stabilisers into solution of hydrogen peroxide. As stabilisers applied are magnesium pechlorate and sodium or potassium silicates, with magnesium pechlorate and sodium or potassium silicates being introduced into hydrogen peroxide solution before addition of hydroxide in the following quantities, mole of substance/mole of hydrogen peroxide: magnesium prechlorate (Mg(ClO₄)₂) 0.0001-0.017; sodium or potassium silicates (Me₂SiO₃) 0.0001-0.028, with addition of hydroxide into stabilised solution of hydrogen peroxide being realised by two portions, and second portion of hydroxide is added after formation of colloid.

EFFECT: simplification of technological process and ensuring stability of hydrogen peroxide alkaline solution for prolonged time.
