摘要
以N-N二甲基甲酰胺（DMF）为溶剂，三乙胺为缚酸剂，丙烯酰氯（AC）为酰化试剂在β-环糊精（β-CD）中引入了双键，并对其进行了傅立叶转换红外光谱（FTIR）和核磁共振波谱（1HNMR）分析，结果证明双键成功地引入到了β-CD中。研究了β-CD与AC的摩尔比、AC与三乙胺的摩尔比、反应时间和DMF溶剂的体积对β-CD-A的双键含量和产率的影响。结果表明，当先在冰水浴条件下反应，然后在室温下反应，n（β-CD）∶n（AC）=1∶8，n（AC）∶n（三乙胺）=1∶1.05，反应时间为1 h，DMF溶液的体积为15 mL每0.5 gβ-CD时，为该实验最佳的反应条件；在此条件下的双键含量为2 mmol/g，产率为60.58%。
An esterification between cationpaper research institute of Faculty Materials and Textiles in Zhejiang University of Science and Technology, 1HNMR. It was testified that the esterification has successfully happened. Studied effect ofβ-CD/AC mole ratio, AC/triethylamine mole ratio, reaction time and the volume of DMF to double bond content and productivity of β-CD-A , it was indicated that react in ice water first , then react in room temperature, the mole ratio ofβ-CD/AC is 1∶8, the mole ratio of AC/triethylamine is 1∶1.05, the reaction time is 1 h, the volume of DMF is 0.5 g/15 mL. When reacted at the best conditions, the double bond content is 2 mmol/g, the productivity is 60.58%.
