Calcium cyanamide + water reaction - ammonia synthesis | CaNCN hydrolysis

In this method, ammonia (NH3) gas is produced. But this reaction is not a very efficient one to produce ammonia. Ammonia is industrially manufactured by Haber process.

In this tutorial, we are going to discuss about steps of preparing ammonia from calcium cyanamide hydrolysis reaction.

Preparing calcium cyanamide | CaC2 + N2 = CaNCN + C

Calcium carbide (CaC2) is heated with nitrogen gas stream at 10000C. It gives calcium cyanamide ( CaNCN) and carbon. This mixture is called nitrolime.

Calcium carbide production process

This reaction is a redox reaction (oxidation reduction reaction).

Nitrogen gas is reduced and carbon atoms are in the carbide are oxidized.

Hydrolysis of calcium cyanamide

Hydrolysis of calcium cyanamide will release ammonia gas slowly. Also calcium carbonate (CaCO3) is given as a product. CaCO3 is deposited as a white precipitate.

Uses of nitrolime

Nitrolime is used as a fertilizer.
