China's abundant coal resources are the raw materials for the production of many important chemicals, such as calcium carbide-acetylene industry , .Currently, China is the The ethyne gas prepared by the above method contains impurities of H 2 S, PH 3, NH 3, AsH 3 etc. due to the contaminations of calcium carbide. Therefore, the gas is passed through acidified solution of CuSO4 which remove the impurities as follows: Two methane (CH 4) molecules connect forming a triple bond when the hydrogen atoms in the CaC 2 + 2H 2 O C 2 H 2 + Ca (OH) 2. Write the chemical equations of the reactions for converting it to ethane. Ethyne can be prepared when methane is subjected to partial combustion at high pressure. Add 1 drop of deionized water on top of the

Ethyne is produced on an industrial scale from calcium carbonate (limestone) and coal: CaO + 3C CaC 2 + CO. Calcium carbide and water are then reacted to produce ethyne and calcium hydroxide: CaC 2 + 2H 2 O Ca(OH) 2 + C 2 H 2. Ethyne can also be manufactured by the partial combustion of methane with oxygen, or by the cracking of hydrocarbons. Procedure. Preparation of ethyne. Set up the apparatus as shown in the diagram. Quicklime is obtained by introducing limestone to heat. CaC 2 + 2H 2 O -----> C 2 H 2 + Ca(OH) 2 Procedure: Lumps of calcium carbide are placed on Calcium carbide is an inorganic compound.
