Sodium Pyrophosphate Decahydrate

Sodium Pyrophosphate Decahydrate



1、Chemical Name: Sodium Pyrophosphate

2、Molecular Formula : Na4P2O7 ; Na4P2O7·10H2O

3、Molecular Weight: Anhydrous:265.90 ; Decahydrate:446.10

4、CAS: Anhydrous:7722-88-5 ; Decahydrate:13472-36-1

5、Character: Decahydrate is colorless or white crystal or white crystalline powder. Anhydrous is white powder. It’s soluble in water, insoluble in ethanol or any other organic solvents. Aqueous solution is alkaline. Its’ chelating capacity of metal ions such as Cu2+, Fe3+, Mn2+ is very active.

6、Usage: It is used as quality improver, pH regulator, chelating agent, emulsifier and binder in food industry. For meat and aquatic products, it could improve water holding capacity to keep them tender; stabilize natural pigment and prevent fat from corrosion. It also can be used in production of baking powder and cheese.

7、Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.

8、Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.
