calcium carbide

h.s.code: 28491000

casno.: 75-20-7

molecular formula: cac2

property: grey, brown or black solid, purple whenits purity is higher, the specific gravity is 2.22(18 ), meltingpoint is 2300 , the product can absorb water in the air and conductelectricity. they higher its purity is, the easier it conducts, itdissolves in water, turns into acetylene and calcium hydroxide andreleases heat.

use: calcium carbide is an important basicmaterial in organic synthesis industry, acetylene obtanied fromcalcium carbide is raw material to make ethylene, chloroprenerubber, calcium cyanamide, acetic acd, acetaldehydr, ethylacetate,cyanide acetate, dicyandiamide, acetone, octanol, trichlorideethylene etc. also used as desulfurizer and dehydrant of steel andfor cutting and welding metals.
