摘要： beta-cyclodextrin butenate was synthesized by using N, N '-Carbonyldiimidazole ( CDI) activating reagent and 4-Dimethylaminopyridine (DMAP) as catalyst. The best preparation condition of beta CD butenate was described as below: reaction temperature was 25 degrees C, concentration of 2-butenoic acid was 450 mmol/L, concentration of DMAP was 12.5 mmol/L and reaction time was 20 minutes and at this condition the yield of beta-CD butenate was 0.83 mmol/g. According to the results of FT-IR spectrum, NMR spectroscopy and HPLC-QTof-mass spectrum of beta-CD butenate, there were four types beta-CD butenate synthesized, which were beta-CD-2-butenoic acid monoester, beta-CD-2-butenoic acid diester, beta-CD-2-butenoic acid triester and beta-CD-2-butenoic acid tetraester, respectively.
