(1) Acetylene generated from the reaction of Calcium Carbide
and water can synthesize many organic compounds such as synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc. Meanwhile, the acetylene-oxygen flame is widely used for metal welding and cutting.
(2) heated powdered calcium carbide and nitrogen, the reaction generates calcium cyanamide, Lime
CaC2 + N2 → CaCN2 + C, ΔH = -296 kJ / mol
Lime nitrogen is an important raw material for preparing cyanamide. Lime nitrogen and salt heating reaction melt used for gold mining and non-ferrous metals industry.
(3) Calcium carbide itself can be used in the steel industry desulfurization agent.
(4) Production of polyvinyl chloride (PVC) and calcium carbide production of polyvinyl chloride Using calcium carbide (CaC2) and acetylene (C2H2) in water to produce vinyl chloride monomer (CH2 = CHCl), and then through the polymerization reaction of vinyl chloride to generate polyvinyl chloride - [CH-CHCI] n- chemical reaction method.
(5) old miners under the mine, the calcium carbide into the iron cans generated by the use of acetylene (C2H2) made of calcium carbide lamps.
