Abstract
In this work we compare the relaxation properties of pure dehydrated glycerol with those of the glycerol usually studied (the glycerol sample which is not specially protected from water absorption). We show that the dielectric spectroscopy can distinguish between the different structures and dynamics of these two kinds of glycerol. We report a relaxation dynamic in the pure dehydrated glycerol crystalline phase. We also show that the crystallization of the pure dehydrated glycerol near 263 K is accompanied by a specific process, which is observed in glycerol without a crystalline phase, by differential scanning calorimetry.
