5、Character: Anhydrous is a white crystalline powder, relative density 2.53, melting point 851 ℃, heated to 400 ℃ decomposition. Insoluble in ethanol, soluble in water, dissolved when heat, solution is strongly alkaline. Easily deliquescence agglomeration in the air, absorb CO2 and produce sodium bicarbonate. Monohydrate as a fine white crystal or powder, the relative density of 1.55. Stable at room temperature and heated to lose crystal water becomes anhydrous at 100 ℃. Decahydrate colorless transparent crystallization temperature 34 ℃, relative density (20 ℃) 1.44, in the air easily weathered.
6、Usage: It is one of the important chemical raw materials used in making chemicals, cleaning agents, detergents, but also for photography and manufacturing pharmaceuticals products.
7、Packing: It is packed with polythene bag as the inner layer, 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 dark, dry and ventilative warehouse, kept away from water and moisture; unloaded with care to avoid damage. Furthermore, it must be stored separately from poisonous substances.
