1、Chemical Name: Ferrous Oxalate
2、Molecular Formula: FeC2O4·2H2O
3、Molecular Weight: 179.91
4、CAS: 6047-25-2
5、Character: It is light yellow powdery crystal, stable at normal temperature and pressure, melting point 160℃ (decomposition), relative density 2.28. Loss of crystal water at 142℃ under vacuum. Solubility in cold water is 0.22g/100g and in hot water is 0.026g/100g, which can be dissolved in cold salt solution. Insoluble in water, slowly soluble in cold hydrochloric acid.
6、Usage: It’s used as analytic reagent, developer and it could also be used in pharmacy and the production of Lithium Ferrous Phosphate (a new type of battery material).
7、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.
8、Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.
