WebIn acidic conditions, aniline is protonated to form its conjugate acid, which is a better nucleophile than the neutral aniline molecule. Explanation: This protonated intermediate attacks the nitronium ion (NO2+), formed from nitric acid and sulfuric acid, to give the meta-nitroaniline product. WebFirst, benzene is nitrated using a concentrated mixture of nitric acid and sulfuric acid at 50 to 60 °C, which gives nitrobenzene.In the second step, the nitrobenzene is hydrogenated, typically at 600 °C in presence of a nickel catalyst to give aniline. As an alternative, aniline is also prepared from phenol and ammonia, the phenol being derived from cumene.
