電石是有機合成化學工業的基本原料之一,是乙炔化工的重要原料。電石與水反應生成的乙炔可以合成許多有機化合物,例如:合成橡膠、人造樹脂、丙酮、烯酮、炭黑等;同時由電石制取的乙炔一氧焰廣泛應用於金屬焊接和切割。電石本身還可用於鋼鐵工業的脫硫劑。
Calcium carbide is one of the basic raw material for organic synthesis chemical industry, also an important raw of acetylene chemical industry. The acetylene reacted by calcium carbide and water can be composed of many organic compounds, such as Synthetic rubber, artificial resins, Acetone, Ketene and carbon black, etc. While acetylene monoxide flame which taken by the calcium carbide is widely used in metal welding and cutting. Calcium carbide can also be used in iron and steel industry as desulfurization sorbent .
