Applications:
Calcium carbide is one of the basic raw material of organic synthesis industry.It is also an important raw material of acetylene industry.
- The reaction of calcium carbide with water, producing acetylene and calcium hydroxide.[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.
eg.synthetize rubber,synthetic resin,acetone,ketene and carbon blace.Meanwhile oxygen-acetylene flame is widely used in metal welding and cutting.
- Heating powdered calcium carbide and nitrogen to producing calcium cyanamide,which can react with sodium chloride producing black cyanide.
black cyanide is used in gold mining and non-ferrous metal industry.
- Steelmaking: as a powerful deoxidizer at ladle treatment facilities.
- Calcium carbide is used in carbide lamps, in which water drips on the carbide and the acetylene formed is ignited.
- In the ripening of fruit, calcium carbide is sometimes used as source of acetylene gas, which is a ripening agent similar to ethylene.
