How can traces of phenol present in a sample of benzene be removed ?

Text Solution

Verified by Experts

If the sample of benzene containing traces of phenol (acidic in nature ) is shaken with 10% NaOH solution then phenol reacts with NaOH to form sodium phenoxide which dissolves in the aqueous layer. The aqueous layer is then removed . In this way traces of phenol present in a sample of benzene can be removed.
