physical property

Physicochemical properties of ammonium formate

Melting point: 115-120 ℃

Solubility: soluble in water, alcohol and ammonia.

Acidity and alkalinity: its aqueous solution is weakly acidic because ammonium ions undergo weak hydrolysis.


chemical property

It decomposes when catalyzed by phosphorus pentoxide at 180 ℃. Hydrogen cyanide gas and water are produced. Phosphorus pentoxide is a dehydrating agent and catalyst.

Hcoonh4 (P2O5 Catalysis) = 2H2O + HCN

Ammonium formate can be used as a reducing agent to reduce unsaturated bonds
