(1)Calcium carbide is an important basic material in organic synthesis industry, Acetylene obtained from calcium carbide is raw material to make ethylene, chloroprene rubber, calcium cyanamide, aceticacid, acetaldehydr, ethylacetate, cyanideacetate, dicyandiamide, acetone, octanol, trichloride ethylene tec.
(2)Also used as desulfurizer and dehydrant of steel and for cutting and welding metals.
3. Property: Grey, brown or black solid, purple when its purity is higher, the specific gravity is 2.22(18), melting point is 2300, the product can absorb water in the air and conduct electricity. They higher its purity is, the easier it conducts, it dissolves in water, turns into acetylene and calcium hydroxide and release heat.
4. Cautions during transportion
The packing must be kept in good condition and the goods should be stored in a dry, cool and ventilated place. It should be separate from the cargo can burn and acid. It should avoid meeting water and moisture. It should give off the acetylene in iron drum before storing in warehouse. Rolling drums, heavy putting down and colliding are not allowed to avoid the spark leads to explosion.
5. Contact method
