【Abstract】 The modified wet-process of preparation for sodium percarbonate and itsprospect are discussed in the paper. According to Na2CO3-H2O2-H2O ternary phase diagram,the stable sodium percarbonate is prepared by the addition of anhydrous sodium carbonate tohydrogen peroxide(30%wt. ) with a suitable ratio of Na2CO3 to H2O2 at 0～20℃, while usingthe composite stabilizer composed of Na2SiO3, MgSO4, EDTA. The results indicate that themcxlified wet process is superior to the others on quality of product and yields.更多还原
