Add calcium carbide into water. You can see a smoke is coming out of water. This smoke is the acetylene gas which is highly flammable. Acetylene''s IUPAC name is ethyne.
Calcium carbide is a chemical compound with the chemical formula of CaC2. Its main use industrially is in the production of acetylene and calcium cyanamide. Applications of calcium carbide include manufacture of acetylene gas, and for generation of acetylene in carbide lamps; manufacturer of chemicals for fertilizer; and in steelmaking.
Calcium Carbide Manufacturing General Calcium carbide (CaC2) is manufactured by heating a lime and carbon mixture to 2000 to 2100°C (3632 to 3812°F) in an electric arc furnace. At those temperatures, the lime is reduced by carbon to calcium carbide and carbon monoxide (CO), according to the following reaction: CaO+3C→CaC2 +CO
Silicon carbide is widely used as a deoxidizer in the steelmaking industry. After a lot of experiments in the smelting process, we learned that the reaction of deoxidizing through silicon carbide is shorter than the reaction time of ferrosilicon, carbon powder, and calcium carbide powder.

Abstract. A laboratoryscale spoutfluid bed reactor with a dc plasma torch was used to study the solidphase synthesis of calcium carbide. Calcium oxide powder with a mean particle size of 170 μm was reacted with graphite powder (130 μm).
At Carbide Industries, calcium carbide production in different sizes (grades) is all we do. Generally speaking, the different grades of carbide that we make correspond to different reactivities of the carbide. For example, we produce fastacting carbide powder that is injected into molten iron to combine with and remove sulfur.
Calcium carbide is a chemical compound with the chemical formula of CaC 2. The material is colorless, but most samples have a color ranging from black to grayishwhite, depending on the grade. Its main use industrially is in the production of acetylene and calcium cyanamide. »

Production. Calcium carbide is produced industrially in an electric arc furnace from a mixture of lime and coke at approximately 2,200 °C (3,990 °F). This is an endothermic reaction requiring 110 kilocalories (460 kJ) per mole and high temperatures to drive off the carbon monoxide. This method has not changed since its invention in 1892: CaO + 3 C → CaC 2 + CO
The modern technology used for the production of calcium carbide is based on the reduction of calcium oxide (lime) to CaC 2 by carbon for the overall reaction CaO + 3C = CaC 2 + CO. During this process, impurities such as sulfur and phosphorus, contained in the charge components, are also reduced and dissolved in molten calcium carbide. Calcium and sulfur form a sufficiently strong .
