Calcium carbide has the following uses:

1, calcium carbide and water reaction to generate acetylene, can be synthesized many organic compounds, such as: synthetic rubber, artificial resin, acetone, enone, carbon black, etc.

2, heating powder calcium carbide and nitrogen, calcium cyanide, namely lime nitrogen; Lime nitrogen is an important raw material for the preparation of cyanuric acid. The melt produced by the reaction of heated lime nitrogen with salt is used in gold mining and non-ferrous metal industry.

3. Calcium carbide itself can be used as a desulfurizer in the iron and steel industry.

4, the production of polyvinyl chloride (PVC) : calcium carbide method production of PVC using calcium carbide (CaC2), water generated acetylene (C2H2), acetylene and hydrogen chloride (HCl) synthesis of vinyl chloride monomer (CH2=CHCl), and then through polymerization reaction to make vinyl chloride into polyvinyl chloride - [CH2 - CHCI] N - chemical reaction method.

5, the old miners under the mine, the calcium carbide into the tin using the generated acetylene (C2H2) made into calcium carbide lamp.
