Ammonium Bicarbonate

AKA: 1066-33-7, Ammonium hydrogencarbonate, Ammonium hydrogen carbonate, Monoammonium carbonate, Carbonic acid, Monoammonium salt, Acid ammonium carbonate, Ammonium acid carbonate, Ammonium hydrogencarbonat, Ammonium bicarbonate (1:1)
Synthetic
Clean
OriginSynthesized from ammonia, carbon dioxide, and water through industrial chemical reactions. Produced by combining these compounds under controlled temperature and pressure conditions in reactors.
Ammonium bicarbonate appears as a white crystalline solid having the odor of ammonia. Soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit spread to the environment. Used to make other ammonium compounds, in food processing, and for other uses.
Solubility Freely soluble in water. Insoluble in ethanol
