All kinds of calcium carbide gas evolution

Calcium carbide calcium carbide chemical name, molecular formula is CaC2, the basic raw material of organic synthetic chemistry industry, the use of calcium carbide as the raw material can be synthesized a series of compounds, to provide raw materials for the industry, agriculture, medicine. Calcium carbide is one of the basic raw materials of organic synthetic chemistry industry. Acetylene is an important chemical raw material. Preparation of the calcium carbide acetylene widely used in metal welding and cutting. The reaction of calcium carbide with water to produce acetylene (CaC2 + 2H-OH → Ca (OH) 2 + CH≡CH ↑) may be synthesized many organic compounds, for example: synthetic rubber, artificial resins, acetone, ketene, carbon black, and the like; while acetylene an oxygen flame widely used in metal welding and cutting. When heating powdered calcium carbide and nitrogen, the reaction of calcium cyanamide, namely lime nitrogen, lime nitrogen and heating the reaction of cyanide salt melt for gold mining and non-ferrous metals industries. Calcium carbide desulfurization agent itself can be used for the steel industry.
