Procedure

In a 1,000 mL-volume three-necked flask, 27.3 g of diphenyl oxalate was dissolved in 600 mL of acetone. In the solution, an aqueous solution of 6.76 g of acetic acid and 7.77 g of potassium carbonate in 25 mL of water was dropwise added under stirring for 4 hours. The mixture was then stirred for 2 hours, and the produced precipitate was collected on a filter by suction. The collected precipitate was washed with acetone and dried under reduced pressure to give 19.9 g of potassium phenyl oxalate. These procedures were performed at room temperature.
