A solution was prepared by adding 20.4 g (0.15 mol) of 4-hydroxyacetophenone and 13.0 g (0.08 mol) of hydroxylamine sulfate to 100 mL of water at 70° C. To the solution was added 16.3 mL of 30% ammonium hydroxide which was then heated at reflux for 0.5 h. White crystals formed upon cooling yielding 21.0 g (92.6%) of 4-hydroxyacetophenone oxime.
