Preparation of Aniline via Reduction of Nitrobenzene A wide range of nitrobenzene derivatives can be easily made via regioselective nitration of substituted benzenes Reduction of the nitrobenzene derivatives using tin/hydrochloric acid provides a convenient and high yielding route to a wide variety of

Experimental procedure: Aniline is not soluble in water; so 1 mol equiv of conc HCl (37 HCl by weight in water) is added in order to dissolve the aniline in water add 1 mol equiv anilineof conc HCladd 1 mol equiv of acetic anhydride H2O Erlenmeyer flaskDon't use a beaker! H2O+Cl-PhNH3(all dissolved) homogeneous solution

Scheme 1 The reaction between the aniline and NaNO 2 was conducted into coil-reactor 1 a mesoreactor immersed in cool-ing bath (10 °C) The reactor output containing the diazonium salt entered coil-reactor 2 where the salt was diluted with an organic solvent (methyl t-butyl ether [MTBE] or ?-methylstyr-ene)
