Physicochemical Properties of Large-Ring Cyclodextrins(CD_18~CD_21)

摘要

Cyclomaltooctadecaose(CD_18),cyclomaltononadecaose (CD_19),cyclomaltoeicosaose(CD_20)and cyclomaltoheneicosaose (CD_21) are cyclio oligosaccharides composed of 18,19,20 and 21 D-glucose units,respectively.This report describes the physicochemical properties of CD_18,CD_19,CD_20 and CD_21 in terms of aqueous solubility,surface tension,optical rotation and acid-catalyzed hydrolysis.
