After UTFSE, i see the hive seems to be missing any info on how to make sodium perborate.

Does anyone have any info on this???

Does anyone have any info on this???

Sometimes, you have to look in stores instead of TFSE.

EXAMPLE 1.

A concentrated solution of sodium metaborate (obtained for example by boiling borax with a solution of sodium hydroxide) is allowed to react at a low temperature with a 3% solution of hydrogen peroxide, 90 grams MgSO,.7 1120 [MgSO₄7H₂O] per kilogram of boric acid treated being added to the hydrogen peroxide. The metaborate solution may be added to the hydrogen peroxide either all at once or in portions. The sodium perborate formed is allowed to crystallise out at a low temperature and it is separated from the mother-liquor by filtration or centrifuging, the product obtained washed with cold water and subsequently dried at a low temperature.

Patent GB434991

and

Patent US2491789

describes the prepn of the more active monohydrate.

It is also commonly used as cheap powdered bleach,
Although, it may be somewhat impure,.

Separating this, would be ideal,.

A quick solubility's check should give an answer.....
