Sodium Acid Pyrophosphate(SAPP)

1. Chemical name: Sodium Acid Pyrophosphate, Disodium Dihydrogen Pyrophosphate

2. M. F.: Na2H2P2O7                                                                                                                                       

3. M. W.: 221.94

4. Physical properties: white monoclinic crystal powder. Its relative density is 1.86. It is soluble in water, insoluble in alcohol. It hydrolyzes to orthophosphate when heated in acid medium. It is hygroscopic, forms hexahydrate in damp air, and decomposes to metaphosphate at above 220ºC

5. Quality standard:( FCC-V,GB25567-2010)
