Trisodium Phosphate Anhydrous

Trisodium Phosphate Anhydrous



1、Chemical Name: Trisodium Phosphate

2、Molecular Formula: Na3PO4 ; Na3PO4·H2O ; Na3PO4·12H2O 

3、Molecular Weight: Anhydrous:163.94 ; Monohydrate:181.96 ; Dodecahydrate:380.18

4、CAS: Anhydrous:7601-54-9 ; Dodecahydrate:10101-89-0

5、Character: It is colorless or white crystal , powder or crystalline granule. It’s easily soluble in water but insoluble in organic solvent.The Dodecahydrate lose all crystal water and become Anhydrous when temperature rise to 212 ℃. solution is alkaline,slightly corrosion on skin.

6、Usage: In food processing industry, it is used as buffering agent, emulsifier, anti-caking agent, antioxidant additive, nutrition supplement and metal chelating agent.

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.
