반응 단계
1 g of phlorizin, 10 mL of acetic anhydride and 0.82 g (0.01 mol) of sodium acetate were reacted at 100° C. for 6 hrs. The reaction mixture was cooled and the triacetate derivative of phlorizin precipitated from the solution in the form of a crystalline solid. The crystalline solid was separated by filtration, dissolved in 50 mL of hot methanol, and re-crystallized twice from hot methanol. The reaction yielded 0.6 g of the triacetate. 0.3 g of the triacetate and 1.3 mL of 0.2 M sulfuric acid in 100 mL of water were heated to reflux and refluxed for 3 hrs. The reaction mixture was cooled yielding the triacetate of phloretin in about a 45% yield.
