Reaktionsschritte

78.5 g (0.80 mol) of potassium acetate, 5.0 g (0.08 mol) of acetic acid, and 123.7 g (0.80 mol) of 2-chloroacetophenone were heated under reflux in 500 mL of ethanol for 6 hours. After completion of heating, the reaction mixture was cooled to room temperature, deposited potassium chloride was filtered off, and the ethanol was distilled off in vacuo to obtain a pale brown oily material. This oily material was poured into one litter of water, and a precipitated solid was collected by filtration and recrystallized from methanol to obtain 113.1 g (yield: 79.3%) of 2-acetoxyacetophenone as a pale yellow solid.
