5. Application
Mainly used to produce acetylene gas. It is also used for organic synthesis, oxyacetylene welding etc...Acetylene produced by the reaction of calcium carbide with water can be used to synthesize many organic compounds, such as synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc...Heating the powdered calcium carbide and nitrogen, the reaction of calcium cyanamide, namely lime nitrogen, cyanide salt and lime nitrogen heating melt reaction for mining gold and nonferrous metal industry. Calcium carbide itself can be used in the iron and steel industry desulfurizer. Production of polyvinyl choride(PVC).
