실험 절차

20 g of p-acetaminobutyrophenone are suspended in 40 ml of semi-concentrated hydrochloric acid and the suspension is heated under reflux for 25 minutes and poured into a mixture of 100 ml of ice and 30 ml of concentrated sodium hydroxide solution. The mixture is filtered with suction, then the residue is washed twice with ice-cold water, dried in the atmosphere and recrystallised from methanol/water (20 ml+100 ml). p-Aminobutyrophenone having a melting point of 93°-94° is obtained.
