| 提纯方法 | Recrystallise α-cyclodextrin from 60% aqueous EtOH, then twice from water, and dry it for 12hours in a vacuum at 80℃. It is also purified by precipitation from water with 1,1,2-trichloroethylene. The precipitate is collected, washed and resuspended in water. This is boiled to steam distil the trichloroethylene. The solution is then freeze-dried to recover the cyclodextrin. [Armstrong et al. J Am Chem Soc 108 1418 1986]. [Beilstein 19/12 V 789.] |
