Calcium Carbide CAS 75-20-7
Sinochem is a major Calcium carbide supplier. Meanwhile, our firm staffs a group of experts devoted to your development of China Calcium carbide.
CaC2, a crucial industrial inorganic compound appearing as gray-black blocks with characteristic purplish-gray fracture surfaces, reacts vigorously with water. This hydrolysis generates acetylene gas alongside significant heat release.
-
More economical than alternative acetylene generation methods.
-
More economical than alternative acetylene generation methods.
-
Produces acetylene gas (C₂H₂) upon contact, useful in welding and lighting.
Calcium carbide Description
NAME: Calcium carbide (CaC2)
Synonyms: Calcium acetylide / Calcium ethynediide / Calcium percarbide / Calcium dicarbide
Molecular Formula: C2Ca
Molecular Weight: 64.10
CAS NO.: 75-20-7
Density: 2.22 g/mL at 25 °C(lit.)
Boiling point: 2300°C
Melting point: 447°C
flashing point: N/A
Appearance: Colorless crystal, gray-black mass in industrial products, cross-section purple or gray.
Properties: Industrial products are gray, brown or black solids, and those with a high calcium carbide content are purple. The newly broken surface of calcium carbide is shiny, and it loses its luster and becomes grayish white when exposed to the air due to absorption of water. It can conduct electricity, and the higher the purity, the easier it is to conduct electricity. The chemical properties are very active and can react with many gases and solutions at appropriate temperatures. It decomposes violently in water to produce acetylene gas and calcium hydroxide, and releases a lot of heat. It can also react violently with chlorine, hydrogen chloride, sulfur, phosphorus, ethanol, etc. at high temperatures.
Storage: Store in a cool, dry and well-ventilated special warehouse room, the temperature of the warehouse does not exceed 32 ° C, and the relative humidity does not exceed 75%. Keep away from fire and heat. The package must be sealed and protected from moisture. It should be stored separately from acids and alcohols, and should not be mixed. Storage areas should be equipped with suitable materials to contain leaks.
Safety Protection: In case of accidental contact with eyes, please rinse immediately with plenty of water and seek medical advice.

Calcium acetylide Applications
1. Used in the production of acetylene gas, polyvinyl chloride, lime nitrogen, dicyandiamide, iron and steel desulfurizer
2. It is used for chemical production accounts for about 60%, and the remaining 40% is used for metal welding and cutting. Using calcium carbide as raw material can produce a series of chemical products, such as PVC resin, polyvinyl alcohol, vinyl acetate, neoprene rubber, butanol, octanol, tricyanoethylene, tetracyanoethylene, acetaldehyde, acetylene carbon black, lime nitrogen, etc.
3. The largest use is the production of PVC resin, accounting for 60% of the consumption of it for chemical purposes.
