Do You Convert Ethyne to 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. Ethyne could be directly converted into benzene in the presence of red-hot Cu or Fe.

How would you convert the ethyne compound into benzene?

- Cyclic polymerization of ethyne can be shown as follows: As we can see how an aliphatic compound (ethyne) can give an aromatic one (benzene) making it another important reaction of ethyne for synthetic purposes. Hence, we can convert ethyne into benzene by its cyclic polymerization.

How would you convert ethyne to a benzene B Ethanal or acetaldehyde?

During the catalytic hydrogenation of ethyne, ethene is formed first, which is further reduced in the next step to ethane. Complete step by step answer: Ethyne on hydration in presence of 40% H2SO4 and 1% HgSO4 gives vinyl alcohol, which tautomerize to form acetaldehyde.
