1. Chemical Name:MONOSODIUM PHOSPHATE
2. Molecular Formula: NAH2PO4,NAH2PO4.H2O,NAH2PO4.2H2O
3. Molecular Weight: ANHYDROUS:120.01,MONOHYDRATE:138.01,DIHYDRATE:156.01
4. CAS No.: 7558-80-7(Anhydrous),10049-21-7(Monohydrate),13472-35-0(Di hydrate)
5. Character: It is colorless column crystal,odorless,slight deliquescence.The relative density is 2.04 and melting point is 60°C.It is easily soluble in water but insoluble in ethanol.if heated below 100°C,it can dissolve in crystal water an convert to monohydrate salt.When heated to 100°C,it will lose crystal water and change to anhydrous substances,which will become sodium metaphosphate if 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 bags as liner and a compound plastic woven bag as the outer layer.The net weight of each bag is 25kg.
