Beta-cyclodextrin (β-CD) was partially substituted by 2-octen-1-ylsuccinic anhydride, via its oxyanion prepared from a reaction with NaH in N,N-dimethyl formamide. 13 C and 1 H NMR spectra revealed that the substitution occurred mainly on C-2 hydroxyl group of glycosyl units. In the reaction mixture, three major derivatives with different average degree of substitution (DS) (0...
β-Cyclodextrin (β-CD) polymers were prepared by cross-linking β-CD with maleic anhydride (MA) in anhydrous N,N-dimethyl formamide (DMF) in the presence of NaH. The weight-average molecular weight (M w ) and the chemical structure of the polymers were determined using high performance size exclusion chromatography (HPSEC) with refractive index (RI) and multiangle laser-light scattering (MALLS)...
