Chemical Name: Sodium dihydrogen phosphate 2. Molecular Formula: NaH2PO4 • 2H2O 3. Molecular Weight: **6.*1 4. Character: Clourless column crystal, odourless and with slight deliquescence. The relative density is 2.*4 and melting point is *0℃. It is easily soluble in water and insoluble in ethahol. If heated below **0 ℃, it can dissolve in crystal water and convert to monohydrate salt. If heated to **0℃, it will lose crystal water and change to anhydrous substances, which will become sodium metaphosphate if continue to be heated. 5. Use: In food processing industry, it is used as buffering agent, character improving agent, emulsifier, nutrition supplement, antioxidant additive , brine penetrable agent, sugar clarifier, stabilizer, coagulant, fowl scalding agent. 6. 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 *5kg. 7. Storage & Transport: It should be stored in a dry and ventilative warehouse, kept away from moistrue and hot. Furthermore, it must be stored separately from poisonous substances. Unload with care as to avoid damage.
