- Cyanamide process
Cyanamide process is a process of manufacturing fertilizer calcium cyanamide and ammonia. The reaction runs at high temperatures 1000 - 1100 °C often with catalyst in mixture of nitrogen and calcium carbide, which form calcium cyanamide and carbon:
- CaC2 + N2 → CaCN2 + C
Further produced calcium cyanamide gives together with water steam calcium carbonate and ammonia:
- CaCN2 + 3 H2O → CaCO3 + 2 NH3
