c,T-dependence of the self-diffusion in concentrated aqueous solutions of methyl α- and β-d-glucopyranosides

The self-diffusion coefficients D for methyl α- and β-d-glucopyranosides in aqueous solutions have been measured in the concentration range between 10% and 70% (w/w) glucoside in a wide temperature range. At higher concentrations (c > 40%) the mobility of the water and the glucoside molecules is significantly lower in the α-d-glucoside solutions than in the corresponding mixtures containing the β-anomer.
