HCID 6623Bisphenol A

Procedure

7.56 g of phenol (0.08 mol) and 0.56 g of benzenesulfonic acid (0.0035 mol) and 2.5 g of the resin prepared according to Example 4 (0.01 mol of resorcinol) were charged into a 30 ml reactor fitted with a magnetic stirrer. The reaction mixture was heated to 50°. When the temperature of the reaction mixture had reached 50° C., 0.58 g of acetone (0.01 mol) was introduced very rapidly with the aid of a syringe. Samples withdrawn at various time intervals were assayed by high performance liquid chromatography to determined the yields of bisphenol A and impurities.
