Solidification Properties of Polyalcohols Aqueous Solution Studied by DSC
In order to examine possible relations between freezing properties and the number of hydroxyl groups in solute molecules, a differential scanning calorimeter (Pyris- Diamond DSC) was employed to study the thermal behaviors of polyalcohols aqueous, such as hydration properties, glass transition, and...

| description | In order to examine possible relations between freezing properties and the number of hydroxyl groups in solute molecules, a differential scanning calorimeter (Pyris- Diamond DSC) was employed to study the thermal behaviors of polyalcohols aqueous, such as hydration properties, glass transition, and devitrification. The experimental results show that at the low concentrations hydration behaviors have no disciplinarians. However, at the high concentrations, they accreted as the concentrations increase. At the middle and low concentration, the aqueous solutions formed partially amorphous glassy state. The temperature of partially glass transition did not change with solution concentration. But, at the high concentration, the aqueous solutions formed completely amorphous glassy state and the temperature of glass transition increased with concentration. The distinct otherness in glass transition and devitrification temperature of five polyalcohols reflected the feebleness and power in the aspects of glass transition ability. |
