Calcium carbide is an inorganic substance, the chemical formula is CaC2, the main component of calcium carbide, white crystals, industrial products are gray-black lumps, and the cross section is purple or gray. It reacts violently when encountering water, generating acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxyacetylene welding, etc.
Acetylene produced by the reaction of calcium carbide with water can synthesize many organic compounds such as synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc.; at the same time, acetylene-oxygen flame is widely used in metal welding and cutting.
