Q. On commercial scale phenol is obtained from chlorobenzene. The chlorobenzene needed for the purpose is prepared byRaschig’s process. Which one of the following is Raschig’s process?

AIIMSAIIMS 2013

Solution:

In Raschirg's process, a mixture of benzene vapours, air and hydrogen chloride is passed over heated $CuCl_2$ at $500\,K$
$2C_6H_6 + 2HCl + O_2($ air $) \xrightarrow[500\,K]{CuCl_2}$
$2C_6H_5Cl+ 2H_2O$
