Reaction Conditions

Reaction Steps

Into a reactor was charged 880g of bisphenol-A and 1000g of acetic anhydride. The reaction was heated to about 135° C. and held at this temperature for about 4 hours. The reaction was vacuum distilled for partial removal of acetic anhydride. Analysis of the crude product showed that conversion to bisphenol-A diacetate was 99.9% complete. The material also contained some residual acetic anhydride (less than 600 ppm based on weight of bisphenol-A diacetate as measured by titration with morpholine as described in Siggia and Hana, "Quantitative Organic Analysis via Functional Groups", Fourth Edition, Wiley-Interscience, 1979, pages 231 to 235).
