Uses of calcium carbide:
(1) Reacting with water to bring about ethine.
(2) Reacting with nitrogen to product lime nitrogen.
(3) The desulfurizer in steel industry.
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. Also
used as desulfurizer and dehydrant of steel and for cutting and
welding metals.
Property: Grey, brown or black solid, purple when its purity is
higher, the specific gravity is 2.*2(*8), melting point is ***0,
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.
