this experiment‚ p-aminophenol‚ the amine‚ is treated with acetic anhydride to form acetaminophen‚ the amide. The crude acetaminophen was expected to be dark in color. This was due to the fact that the impurities were formed from oxidation of the starting phenol. The intensity of this was enough to impart color to the crude acetaminophen. Crude acetaminophen can be purified using the solid-liquid separation technique of ccrystallization where there is a transfer of the solute from the liquid solution
