The effect of fecl3 on changes in the rheological properties of glycerol determined by an acoustic method

The results of the shear mechanical impedance measurements are pre-sented for solutions of FeC13 in glycerol at frequencies 30 and 500 MHz and over a temperature range from 218-303 K. These results complemented the previous investigations [4] performed at a frequency of 0.5 MHz. A distinct ef¬fect of FeC13 on the range of the viscoelastic relaxation of glycerol and on its mo¬lecular structure was found.
