Processes for preparing sodium percarbonate |
摘要 |
Improved processes for preparing sodium percarbonate, 2Na2CO3.3H2O2, which can have an apparent density of 0.6 to 1 g/cm3 and a mean particle diameter of 210 to 610 microns, which processes comprise treating a sodium carbonate monohydrate or hydrate having 75 to 90% of Na2CO3 and having a density equal to or even greater than 1.2 g/cm3 with 60 to 80% aqueous hydrogen peroxide, the reaction mixture containing a small quantity of nonionic surfactant stable in hydrogen peroxide and alkaline solutions, the percarbonate formed being well adapted for use in detergent compositions.
