Abstract

Densities of binary aqueous solutions of D-fructose (abbreviated as FR hereinafter) were determined in a much wider mole fraction range than available in literature. In contrast to hydrophobic solutes, the partial molar volume of FR, V-FR, does not show an initial decrease on increasing the mole fraction of FR, x(FR). In order to learn more about the effect of FR on the molecular organization of liquid H2O, the excess chemical potentials and partial molar enthalpy of 1-propanol (1P) were determined in ternary 1P-FR-H2O system. Namely, the detailed thermodynamic behaviour of 1P in the ternary system was used as a probe to elucidate the effect of FR on liquid H2O. In comparison with earlier results of the temperature dependence of tert-butanol (TBA)-TBA interaction functions, addition of FR seems to have a similar effect of temperature increase on the molecular organization of H2O. We suggest that addition of FR tends to decrease the global average of hydrogen bond probability of H2O. (C) 2000 Elsevier Science B.V. All rights reserved.
