Question

how do you convert acetylene into benzene? or cycilc polymerization of ethane. ​

Answer 1

▪️Preparation of benzene from alkynes

Benzene is prepared from ethyne by the process of cyclic polymerization. In this process, Ethyne is passed through a red-hot iron tube at 873 K. The ethyne molecule then undergoes cyclic polymerization to form benzene.

▪️When ethyne gas is passed through the red-hot iron tube, it leads to the formation of cyclic aromatic compound. When acetylene is heated in red-hot iron tube at 873 K, benzene is obtained.
