MONOSODIUM PHOSPHATE

LTW(Jiangsu)LLC

MONOSODIUM PHOSPHATE

Product category: Phosphate

1. Chemical Name: MONOSODIUM PHOSPHATE

2. Molecular Formula: NaH2PO4,NaH2PO4·H2O,NaH2PO4·2H2O

3. Molecular Weight: Anhydrous: 119.98; Monohydrate: 137.99; Dihydrate: 156.01

4. CAS: Anhydrous: 7558-80-7; Monohydrate: 10049-21-7; Dihydrate: 13472-35-0

5. Character: It is  colourless  column crystal, odorless, slightly deliquescence. The relative density is 2.04 and melting point is 60℃. It is easily soluble in water but insoluble in ethahol. If heated below 100℃, it can dissolve in crystal water and convert to monohydrate salt. When heated to 100℃, it will lose crystal water and change its anhydrous substances, which will become sodium metaphosphate if it’s continue to be heated.

6. Usage: In food industry, it is used as buffering, character improving agent, emulsifier, nutrition supplement, antioxidant additive, brine penetrable agent, sugar clarifier, stabilizer, coagulant, fowl scalding agent.

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

8、Storage and Transport: It should be stored in a dry and ventilating warehouse.
