Abstract

La présente invention concerne un procédé de préparation de percarbonate de sodium. On fait agir du peroxyde d'hydrogène concentré sur une suspension fluide de carbonate de sodium décahydraté dans une solution saturée de carbonate de sodium, le carbonate de sodium décahydraté étant en quantité telle que l'enthalpie de dissolution compense l'enthalpie de cristallisation ou de formation du percarbonate de sodium et les autres phénomènes consommant des frigories, en présence d'un modificateur de cristallisation Le procédé est applicable à l'obtention de percarbonate de sodium dont la particule élémentaire est un cristal rhomboédrique régulier.
