WebPhenol is an important chemical material that is widely used in industry. Currently, phenol is dominantly produced by the well-known three-step cumene process, which suffers from severe drawbacks. Therefore, developing a green, sustainable, and economical strategy for the production of phenol directly from benzene is urgently needed. In recent years, the … Web8 apr. 2024 · Complete answer: As we know, the phenol is converted to chlorobenzene by using two steps. First we have to prepare benzene from the phenol. After that, it converts into chlorobenzene. First the phenol is reacted with the zinc dust, then there is a formation of benzene. And this benzene is further reacted in the presence of chlorine gas and iron.
