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.

Production Methods

Nickel Oxalate is produced as a greenish white crystalline dihydrate.

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 μ_eff=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.
