Synthetic
Not Clean
OriginProduced synthetically from ammonia and carbon dioxide through chemical combination. Manufactured via the Solvay process or direct synthesis of ammonia with CO2 gas.
Ammonium carbonate appears as a colorless crystalline solid or a white powder with a strong odor of ammonia. Noncombustible. 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 pharmaceuticals, in food processing.
