Question

Make a brief note about Nitrolium.

Answer 1

Inorganic chemical compounds:

• A chemical substance that lacks carbon-hydrogen bonds is known as an Inorganic compound.
• Calcium Cyanamide's other name is Nitrolium.
• It is the calcium salt of the anion cyanamide $\left({{\mathrm{CN}}_2}^{2-}\right)$.

Nitrolium Preparation:

• Calcium carbide is used to make calcium cyanamide.
• The carbide powder is heated to around ${1000}^{\mathrm{o}}\mathrm{C}$ in an electric furnace that is fed with nitrogen for several hours.
• The product is cooled to room temperature, and any unreacted carbide is carefully leached out with water.
• The reaction for the preparation of Nitrolium is depicted below:

${\mathrm{CaC}}_2\left(\mathrm{s}\right)+{\mathrm{N}}_2\left(\mathrm{g}\right)\to {\mathrm{CaCN}}_2\left(\mathrm{s}\right)+\mathrm{C}\left(\mathrm{s}\right)$

Nitrolium Applications:

• It is used for agriculture purposes as a fertilizer.
• It is fused with sodium carbonate to produce sodium cyanide. In gold mining, in the cyanide process, sodium cyanide is used widely.
