FIELD: chemistry. ^ SUBSTANCE: first, magnesium sulphate, then alkali is added to hydrogen peroxide. When pH value of solution reaches approximately 10, lithium peroxide monohydrate is introduced into it. Then remaining amount of alkali is added to solution. Stabilisers are introduced in the following amounts, mole of substance/mole of hydrogen peroxide: 0.0001-0.017 of magnesium sulphate (MgSO4); 0.0001-0.028 of lithium peroxide monohydrate (Li2O2H2O). ^ EFFECT: increasing time of stability of hydrogen peroxide alkali solution, reduction of hydrogen peroxide consumption and increase of main component content in synthesis product. ^ 3 cl, 1 tbl, 6 ex |
