Abstract

This article focuses on analyzing the solution structure parameter α and the hydration parameter h for sugar alcohols and related sugars in water, using freezing point depression, viscosity, and density measurements. The study demonstrates a strong negative correlation between α, derived from molar fraction and freezing points, and h, calculated from the viscosity B coefficient and partial molar volume, supporting the theoretical relationship α = −h. Results indicate that h depends primarily on the viscosity B coefficient and molecular weight of the solute, with sugar alcohols generally showing hydration behavior similar to their corresponding sugars. Additionally, temperature-dependent measurements suggest that the thermal stability of hydration increases with the molecular weight of the saccharide, regardless of ring structure.
