Ammonium oxalate, also known as diammonium ethanedioate is a chemical compound, with the chemical formula (NH4)2C2O4. It can sometimes be encountered in nature, in guano.
Ammonium oxalate will decompose when heated, to yield oxamide:
- (NH4)2C2O4 → (CONH2)2 + 2 H2O
Ammonium oxalate is a white crystalline solid, soluble in water. It is generally encountered as a monohydrate. Ammonium oxalate has a density of 1.5 g/cm3 at 20 °C.
Ammonium oxalate is sold by many chemical suppliers. Can also be bought online.
Another route involves the hydrolysis of cyanogen, in a neutral or slightly acidic aqueous environment.
- Make oxamide
Ammonium oxalate is harmful if ingested.
In closed bottles, away from acidic vapors.
Ammonium oxalate can be destroyed by reacting it with a base, followed by pyrolysis.
