Conditions

Temperature: 140 °C

Procedure

22.8 g of bisphenol A and 25.5 g of acetic anhydride were introduced into a 150 ml three-necked flask provided with a reflux condenser and a stirrer, and stirred under heating at 140° C. for 7 hours. Then, the obtained reaction product was transferred to a 150 ml flask, and the acetic acid and acetic anhydride therein were removed by heating the mixture to 100° C. under reduced pressure of 10 Torr to obtain 31.1 g of bisphenol A diacetate.
