How to Convert Ethyne to Benzene

Answer:

The production of cyclic aromatic compounds occurs when ethyne gas is pushed through a red-hot iron tube. When acetylene is heated to 873 K in a red-hot iron tube, benzene is produced. In the presence of red-hot Cu or Fe ethyne could be transformed straight to benzene. Each molecule has one link that breaks to connect to the next in a circular manner, similar to how benzene is obtained directly.
