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
