Chemical Name: | Monosodium Phosphate Sodium Dihydrogen phosphate |
Molecular Formula: | NaH2PO4, NaH2PO4·H2O, NaH2PO4·2H2O |
Molecular Weight: | anhydrous: 120.01; Monohydrate: 138.01; Dihydrate: 156.01 |
CAS: | anhydrous: 7558-80-7; Monohydrate: 10049-21-5; Dihydrate: 13472-35-0 |
Character: | It is colorless 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 ethanol. 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 to anhydrous substances, which will become sodium metaphosphate if continue to be heated. |
Uses: | 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. |
Packing: | It is packed with polyethylene bag as liner and a compound paper-plastic woven bag as the outer layer. The net weight of each bag is 25kg. |
