1.Chemical Name: Sodium Phosphate mono basic
2.Molecular Formula: NaH2PO4
3.Molecular Weight: 120.01
4.CAS: 7558-80-7
5.Character: It is colorless column crystal, odorless, slightly deliquescent. The relative density is 2.04 and melting point is 60℃. It is easily soluble in water but insoluble in ethanol. If heated below 100℃, it can dissolve in its’ own crystal water and convert to monohydrate salt. When heated up to 100℃, it’ll lose crystal water and change to anhydrous substances, which will become Sodium Metaphosphate if it continues 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 and fowl scalding 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.
