Yield: 100%
Reaction Conditions:
with potassium carbonate;Diethyl carbonate at 110; for 18 h;
Steps:
I-1 Example I-i. One pot synthesis ofbisp henol A bis(2,3 -dihy droxy p ropy lether (BABDHPE)
In a single necked round bottom flask bisphenol A (10 g, 43.80 mmol), glycerol (24.20 g 262.82 mmol), diethyl carbonate (15.52 g, 131.4 mmol) and potassium carbonate (3 g, 21.70 mmol) were introduced. The flask was connected toa Claisen distillation setup and the reaction mixture was vigorously stirred at 110 °C. After 18 h thereaction was stopped by first applyingvacuum to remove any unreacted diethylether and the ethanol byproduct. The hot reaction mixture was then added to a beaker containing 500 mL deionized water. A viscous reaction product was allowed to settle over time and the sup ernatant water removed. The crude reaction product was washed twice with 500 mL water to remove any unreacted glycerol. The 99% purebisphenol A bis(2,3-dihy droxypropyl)ether was isolated in quantitative yields.
