Excess concentrated sulfuric acid aids with this process as it is a dehydrating agent. ... A published synthesis use 1.075 mol aniline and 1.122 mol sulfuric acid, so there is only 0.044 mole excess of sulfuric acid. Further, the reaction is conducted at ~200 ºC so the water that forms will be distilled off.
