There is a mixture of aniline and phenol. I need to obtain (just the procedure) pure aniline.

So I think the mixture should heat with Zn powder(to convert phenol to benzene) and then I thought to synthesize aniline from benzene.

I am not sure about this method?

Please help me

    $\begingroup$ Is the objective to remove the phenol from the mixture, or to convert phenol to aniline. It is fairly easy to purify the aniline from the mixture. $\endgroup$

    $\begingroup$ I would try to dissolve the mixture in dichloromethane, then extract phenol with concentrated water solution of sodium hydroxide and finally precipitate aniline from ethanol or methanol with water. Even though working with sodium hydroxide requires goggles, you can care less about inhaling its fumes, unlike concentrated HCl. Re-synthesis is usually a very unvise choice even for moderately complex aromatics. $\endgroup$

First dissolve phenol and aniline in diethyl ether and add excess HCl solution . Then aniline will react with HCl and dissolve in water layer. Easily remove organic layer.

Take the water layer and add excess NaOH to it and aniline will be precipitated.
