Calcium carbide (CaC2) is a pivotal inorganic compound known for its industrial form as gray-black block-like material, often displaying purple or gray cross-sections. When exposed to water, it undergoes an energetic reaction, producing acetylene gas and releasing heat. Primarily, it's employed for two key purposes: as a source of acetylene gas with applications in welding, cutting, and fuel, and as a raw material in organic synthesis for chemicals like vinyl chloride and synthetic resins.
Used in the production of acetylene gas, polyvinyl chloride, lime nitrogen, dicyandiamide, iron and steel desulfurizer, etc., used in electronics industry, teaching reagents. Calcium carbide 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.
Calcium carbide is an inorganic compound, white crystal, industrial products are gray black blocks, cross-section purple or gray. It reacts violently with water, 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, oxyacetylene welding and so on. It is called calcium carbide( CaC2). It is a hard lump and the cross section is dark grey or brown. 2. It is lumpy substance, its surface is a little deep gray, has slight nasty smell. 3. It can produce acetylene gas when met water, it can burn when meets fire. 4.The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is 2.3% - 81%). 1.The main raw material for producing acetylene gas. 2.Cutting and welding for metal material. synthesize polyvinyl chloride(PVC). 4.Fruit catalyst. 5.The basic material for organic synthesis and calcium cyanamide 6.Reacting with water to bring about ethine. 7. Reacting with nitrogen to product lime nitrogen. 8.The desulfurizer in steel industry.
