1,Chemical Name:Disodium phosphate
2,Molecular Formula:, Na2HPO4,Na2HPO4·2H2O,Na2HPO4·12H2O
3,Molecular Weight: Anhydrous: 141.99; Dihydrate: 177.96;Dodecahydrate: 358.14
4,CAS: Anhydrous: 7558-79-4; Dihydrate: 10028-24-7; Dodecahydrate: 10039-32-4
5,Character: It is white or colorless rhombic crystalline or prismatic crystal. It's easily soluble in water, but insoluble in ethanol. The relative density is 1.63 and melting point is 34.6ºC. If heated to 180ºC, it may lose crystal water and convert to anhydrous.
6,Usage: In food industry, it is used as agent for baking to avoid oxidation stain and asemulsifier in dairy product to prevent egg white fromsolidification. It is also used as emulsifier and chelating agent for solid drinks.
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 ventilatingwarehouse, kept away from moisture and heat. Furthermore, it should be stored separately from poisonous substances; unload with care so as to avoid damage to packing.
