First, what is calcium carbide

Calcium carbide generally refers to calcium carbide, calcium carbide, chemical formula: CaC2, namely calcium carbide, inorganic compounds. White crystal, industrial grayish-black mass with purple or gray cross section. In contact with water, a fierce reaction occurs immediately, forming acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxylene welding and so on.

Second, the purpose

(1) Many organic compounds can be synthesized from acetylene produced by the reaction of calcium carbide with water

For example: synthetic rubber, artificial resin, acetone, enone, carbon black, etc.; At the same time acetylene oxygen flame is widely used in metal welding and cutting.

(2) When heated powdery calcium carbide and nitrogen react to produce calcium cyanide, namely lime nitrogen. The cyanide melt generated by heating lime nitrogen and salt reaction 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) production of polyvinyl chloride (PVC), calcium carbide production of PVC using calcium carbide (CaC2), water generated acetylene (C2H2), acetylene and hydrogen chloride (HCl) synthesis of vinyl chloride monomer (CH2CHCl), and then through polymerization reaction to make vinyl chloride into polyvinyl chloride - [CH CHCI] N - chemical reaction method.

(5) the old miners down the mine, the calcium carbide into the iron can weave using the generated acetylene (C2H2) made into calcium carbide lamp.

Three, storage method

Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat source. Keep relative humidity below 75%. The package must be sealed and protected from moisture. Should be stored separately from acids and alcohols, and do not mix storage. The storage area shall be equipped with suitable materials to hold the leakage. The best way is to put in a high strength moisture-proof box, maintain a stable humidity.
