純化方法Check the NMR spectrum. If it is not satisfactory, then add Ac2O and a drop of conc H2SO4 and heat at 50o for 10minutes. Then add anhydrous NaOAc (ca 3g/ 100g of liquid) and fractionate. Note that it forms an azeotrope with H2O, so do not add H2O at any time. It is a highly flammable and TOXIC liquid; keep away from the skin. [Smith et al.
