1. Chemical Name : Zinc Acetate Dihydrate
2. Molecular Formula : (CH3COO)2Zn·2H2O
3. Molecular Weight : 219.499
4. CAS : 5970-45-6
5. Einecs : 209-170-2
6. Character : Stable under normal temperature and pressure, white monoclinal crystal with pearl luster and taste of acetic acid. Soluble in water and ethanol. Crystal water was lost at 100℃, and the anhydrous substance was white monoclinic crystal. When the temperature is high, acetone is formed. It is easily soluble in water and its aqueous solution is weakly acidic with a pH value of about 5.6. Soluble in ethanol. Heating to 100℃ to lose crystalline water into anhydrous matter.
7. Usage : Reagent for determination of sodium, hydrogen sulfide, protein, chromatographic analysis reagent, mordant, used in polyester industry; Used as analytical reagent, chromatographic reagent and mordant.
8. 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.
9. Storage and Transport : It should be stored in a dry and ventilating warehouse, be cautious to keep away from moisture and hot, unloaded with care so as to avoid the damage. Furthermore, it should be stored separately from poisonous substances.
