How do you make P-aminophenol?
PROCEDURE
- Step 1: Preparation of n-Phenyl hydroxyl amine from Nitrobenzene. In a 2 litre beaker, equipped with a thermometer and mechanical stirrer, place 25 g of ammonium chloride, 800 ml of water and 50 g (41.6 ml, 0.41 mol) of redistilled nitrobenzene.
- Step 2: Preparation of p-Aminophenol from n-Phenyl hydroxyl amine.

How is 4-aminophenol formed?
It is produced from phenol by nitration followed by reduction with iron. Alternatively, the partial hydrogenation of nitrobenzene affords phenylhydroxylamine, which rearranges primarily to 4-aminophenol: C6H5NO2 + 2 H2 → C6H5NHOH + H2O.
