ACYCLIC CARBONATES OF BETA-CYCLODEXTRIN

The synthesis of acyclic carbonates of beta-cyclodextrin obtained from the reaction of alkyloxycarbonylimidazole with beta-cyclodextrin, is described. The reaction gave a mixture of linear carbonates which were characterized via TLC, HPLC, C-13 NMR and FT-IR. No cyclic carbonates have been detected. The products obtained are low-melting, surface ac tive, easily soluble in water and show good inclusion properties. Thei r average degree of substitution varies depending on the reaction cond itions used.
