Abstract

L'invention concerne un procédé de fabrication de percarbonate de sodium. Il est caractérisé par le fait qu'on incorpore le reste des réactifs à une suspension de percarbonate préparée suivant cette réaction à partir de seulement 3 à 50 % en poids, de préférence 5 à 20 % en poids, de suspension de soude et de solution de H2 O2 mise en oeuvre au total, cela en ajoutant à cette dernière suspension, de façon continue et en agitant, une suspension de soude contenant du NaCI et/ou du Na2 SO4 et, le cas échéant, du peroxyde résiduel et, en même temps, une solution de H2 O2 contenant du Mg** 2+, ainsi que de l'hexamétaphosphate de sodium, en continuant d'agiter. L'invention s'applique à l'industrie des détergents.
