Dielectric and hydrogen bonding studies of butyronitrile with 1,4-dioxane using a time-domain reflectometry
Using time-domain reflectometry (TDR), the complex permittivity of binary mixture of butyronitrile (BTN) and 1,4-dioxane (1,4-DX) at various temperatures and solvent proportions was determined over the frequency range of 10 MHz to 30 GHz. The complex permittivity spectra (CPS) have been fitted to the Havrilik–Negami equation. The relaxation time (τ) and static dielectric constant (ε0) have been calculated for each concentration using the least squares fit method. The nonlinear behavior of dielectric parameters suggests a change in the molecular size and intermolecular bonding of BTN–1,4-DX mixtures. Theoretical static dielectric constants (ε0) have been determined using hydrogen bonded model suggested by Luzar for all solvent proportions and compared with experimental values obtained from TDR.
