Structure of aqueous solutions of sucrose, derived from viscosimetry data and IR spectroscopy

Аннотация

The structural features of aqueous sucrose solutions are investigated via viscosimetry and IR spectroscopy in the 293.15–323.5 K range of temperatures at concentrations of 0–60%. Concentration dependences of the activation parameters of viscous flow, structural temperature, and energy and length of intermolecular hydrogen bonds are calculated based on the experimental data. It is shown that the solution became more structured with an increase in the sucrose concentration.
