The three aminophenol isomers: Left: 2-Aminophenol (o-aminophenol) Center: 3-Aminophenol (m-aminophenol) Right: 4-Aminophenol (p-aminophenol) Aminophenol may refer to any of three isomeric chemical compounds: 2-Aminophenol; 3-Aminophenol; 4-Aminophenol; They are simultaneously an aniline and a phenol
The classical methods for the production of paracetamol involve the acetylation of 4-aminophenol with acetic anhydride as the last step. They differ in how 4-aminophenol is prepared. In one method, nitration of phenol with nitric acid affords 4-nitrophenol, which is reduced to 4-aminophenol by hydrogenation over Raney nickel.
