| | NICKEL OXALATE DIHYDRATE Usage And Synthesis |
| Chemical Properties | light green powder(s) . Nickel(II) Oxalate Dihydrate [6018-94-6], Ni(COO)2·2 H2O, Mr 182.76, precipitates as a green powder when oxalic acid or alkali-metal oxalate solutions are added to nickel(II) salt solutions. When heated in vacuum, it evolves water at 150 ℃ and decomposes completely at 300 ℃, giving finely divided nickel suitable for use in catalysis or in the production of nickel carbonyl. | | Uses | Nickel oxalate is used for the production of nickel catalysts and magnetic materials. | | Uses | It is an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuffs. | | Preparation | Nickel(II) oxalate precipitates as NiC2O4?2H2O when oxalic acid is added to nickel
salt solutions. It is isomorphous with the oxalates of magnesium, zinc and iron(II), and has
μeff=2.95 BM. When heated in vacuo it decomposes evolving water above 150° and
carbon dioxide above 300° leaving finely divided nickel suitable for catalytic purposes or
reacting to form the carbonyl. The oxalate dissolves in acids with decomposition and in
ammonia with ammine formation. | | Production Methods | Nickel Oxalate is produced as a greenish white crystalline dihydrate. |
