Abstract:
Processes for the preparation of sodium percarbonate having substantially the formula 2Na2CO3.3H2O2, the processes being particularly suited to the use of ordinary sodium carbonate, which processes comprise reacting 60 to 80 percent hydrogen peroxide with sodium carbonate monohydrate or a hydrate of sodium carbonate containing from about 75 to 90 percent sodium carbonate; and products obtained thereby, particularly those percarbonate products having an excellent resistance to shock and attrition and effective densities of 0.61-0.92 g/cm3 and mean particle diameters of 250-610 microns.
