Abstract

Air oxidation of α-cyclodextrin, β-cyclodextrin and γ-cyclodextrin with platinum-asbestos catalyst was attempted. The oxidation products were separated with GPC on Toyopearl HW-40S for γ-cyclodextrin (eluent: water) and on HW-50S for a-cyclodextrin (eluent: water) and β-cy-clodextrin (eluent: 10% methanol). The yields of oxides for the three species (α-, β- and γ-cy-clodextrin) estimated from GPC were 17.7, 10.8 and 23.4%, respectively. However, HPAEC analysis proved that the oxides of the three species were mixtures of regio-isomers.
