6.Other Information

Usage: It is an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuffs.

Merck: 14,6514

Chemical Properties: light green powder(s) [MER06]

Uses: Nickel oxalate is used for the production of nickel catalysts and magnetic materials.

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.
