文摘
The densities, 蟻, and viscosities, 畏, of some mono-, di-, and trisaccharides in (0.05, 0.10, 0.12, and 0.15) mol路kg鈥? aqueous disodium tetraborate (borax) solutions have been determined at (288.15 to 318.15) K, by using a vibrating-tube digital densimeter and an Ubbelohde-type capillary viscometer, respectively. From these data, the standard partial molar volumes at infinite dilution, V2掳 and Jones-Dole viscosity B coefficients have also been evaluated. Their significantly large positive values vary with the size of saccharides, i.e., from mono- to di- to trisaccharides. The results have been discussed in terms of the solute鈥揷osolute interactions occurring in these solutions.
