| 摘 要： | 根据Malaprade反应的原理,采用高碘酸盐氧化γ-环糊精的方法制备双醛γ-环糊精,探讨了p H值、高碘酸钠与γ-环糊精摩尔比、反应温度、反应时间对双醛γ-环糊精中醛基含量的影响.结果显示,在高碘酸钠与γ-环糊精的摩尔比为1、p H值为2、反应时间3 h、反应温度在30~35℃之间的条件下,采用将高碘酸钠固体溶解后投入到γ-环糊精溶液中的方法投料,可得到双醛γ-环糊精.

| Abstract: | Based on the Malaprade reaction,this research studies the techniques for preparing dialdehyde cyclodextrin through the periodate- oxidized γ- cyclodextrin dialdehyde cyclodextrin,and the impacts of its p H value,the ratio of sodium periodate and the γ- cyclodextrin molar,the reaction temperature,the reaction time on the dialdehyde- γ- cyclodextrin content. The results show that when the p H value is 2,the ratio of sodium periodate and the γ- cyclodextrin molar is 1∶ 1,the reaction temperature is between 30—35 ℃ for 3h,and the dissolved solid of sodium periodate is put into the γ- cyclodextrin solution,the dialdehyde γ- cyclodextrin can be obtained. |
