Applications of calcium carbide
1 Production of acetylene
The reaction of calcium carbide with water, producing acetylene and calcium hydroxide, was discovered byFriedrich Wö Hler in 1862.
CaC2 + 2 H2O C2H2 + Ca(OH)2
This reaction was the basis of the industrial manufacture of acetylene, and is the major industrial use of calcium carbide.

2 Production of calcium cyanamide
Calcium carbide reacts with nitrogen at high temperature to form calcium cyanamide:
CaC2 + N2 CaCN2 + C
Calcium cyanamide is used as fertilizer. It is hydrolysed to cyanamide, H2NCN.

3 Other uses
In the artificial ripening of fruit, calcium carbide is sometimes used as source of acetylene gas, which is a ripening agent similar toethylene. However, this is illegal as consumption of fruits artificially ripened using calcium carbide can cause serious health problems in those who partake them.
