Abstract

"Process for the preparation of flowable and abrasion resistant sodium perborate" with a bulk density of 0.75 to 0.85 kg/l by reaction of a solution of sodium metaborate with hydrogen peroxide in an aqueous suspension of sodium perborate, characterized in that the participants in the reaction are continuously introduced into the reaction vessel and the crystallization is carried out in the transparent mother liquor with a molar ratio of NaBO2: H2O2 from 1: 0.35 to 1: 0.1, the crystalline suspension is continuously withdrawn from the reaction vessel in an amount corresponding to the introduced quantity of NaBO2 and H2O2, the crystals are separated from the mother liquor and dried.
