Versuchsvorschrift
A vigorously stirred suspension of thallous phenoxide (5 g., 0.017 m.) in anhydrous ether (15 ml.) is treated dropwise with freshly distilled acetyl chloride (1.33 g., 0.017 m.) in anhydrous ether (3 ml.) over 5 mins. at such a rate that the exothermic reaction is controlled. The mixture is then stirred for 1 hour at room temperature, the precipitated thallous chloride removed by filtration through Celite and the solvent evaporated under vacuum. The residual colorless oil is distilled to give phenyl acetate, 2.27 g., 98%, b.p. 110°/58 mm.
