anhydrous silicate
1.Sodium percarbonate,which contained more than 13% effective oxygen,could be prepared by reaction of 20% H 2O 2 solution and industrial grade anhydrous sodium carbonate by a one step liquid solid phase reaction,using a new type of inner stabilizer A and magnesium silicate as outer stabilizer. The content of the effective oxygen of the product was more than 14 5%,and the content was still more than 13 5% after 3 month preservation.
