Phenol from aniline
Web13. jan 2024 · Preparation of Phenol from Aniline Diazonium salts are obtained on treating primary aromatic amines with nitrous \ (\left ( { {\rm {NaN}} { {\rm {O}}_2} + {\rm {HCl}}} \right)\) acid at \ (273 – 278\; {\rm {K}}\). On warming with water, these diazonium salts finally hydrolyse to phenols. WebThe amination of phenol to aniline is a sustainable method to replace the traditional synthesis of primary aniline by nitrobenzene−hydrogenation and halobenzene−amination. Under a hydrogen atmosphere, the supported Pd catalyst exhibits significant activity in phenol amination with various amines, but the selectivity to primary aniline is poor.
