Versuchsvorschrift
To a stirred solution of 66.0 g (0.60 mole) of 3-aminophenol in 180 mL of water was added dropwise 77.9 g (0.76 mole) of acetic anhydride. After complete addition, the reaction mixture was heated on a steam bath for 10 minutes, then cooled to 0° C. A precipitate formed and was collected by filtration. The filter cake was washed with cold water and dried in a desiccator for two hours to yield 81.0 g of 3-hydroxyacetanilide (mp 144°-146° C.).
