The values of complex permittivity for alcohol−1,4-dioxane (DX) mixtures with various concentrations have been determined in the frequency range 10 MHz to 20 GHz using the time domain reflectometry (TDR) method. Numbers of hydrogen bonds between alcohol−alcohol and alcohol−dioxane pairs are estimated from the values of the static dielectric constant by using the Luzar model. The model provides a satisfactory explanation of the experimental results related to the static dielectric constant. The binding energies for alcohol−alcohol (pair 11) and alcohol−DX (pair 12) are estimated to be −13.98 and −16.25 kJ/mol, respectively. The results have also been compared with previous results of the ethyleneglycol−DX system.
