Abstract

La présente invention concerne la préparation de perborate de sodium anhydre par déshydratation de perborates. Selon le procédé la déshydratation ménagée des perborates est conduite en présence d'air sec décarbonaté avec élévation contrôlée de la température des produits traités. Le procédé est applicable notamment à la déshydratation des perborates couramment désignés par les dénominations monohydrate et tétrahydrate.
