純化方法Dissolve p-ethylaniline in *benzene, then acetylate it. Recrystallise the acetyl derivative (m 93-94o, Hickinbottom & Waine J Chem Soc 1565 1930) from *C6H6/pet ether or EOH, and hydrolyse it by refluxing 50g with 500mL of H2O and 115mL of conc H2SO4 until the solution becomes clear. The amine sulfate is isolated, suspended in H2O and solid KOH is added to generate the free base, which separates. Dry it (KOH), and distil it from zinc dust in a vacuum [Berliner & Berliner J Am Chem Soc 76 6179 1954]. The picrate has m 171-172o (from 1,2-dichloroethane).
