일반 설명
This product has been enhanced for catalytic efficiency.
Purification Methods
It crystallises from aqueous solutions of moderately strong HNO3 as the pale violet nonahydrate m 40o and is soluble in EtOH and Me2CO. With more concentrated aqueous solutions (containing some HNO3), the hexahydrate crystallises out m 60.5o . The anhydrous salt is slightly deliquescent and decomposes at 47o.
