“…For the investigated polar-non-polar solutions a positive deviations of g from unity, which is due to the parallel orientation of the dipoles were obtained. As can be seen from the table, the compounds show a significant degree of parallel molecular association.Values of the effective Kirkwood correlation factor, g ff , and the corrective Kirkwood correlation factor, g f , for the polar-polar binary mixture of (1OCT + 1,3BD) were calculated using modified form of the Kirkwood equation [52][53][54]. The modified form of the Kirkwood equation for the mixtures of two polar liquids may be written as…”

“…In this experimental study, formamide (FMD) is considered as liquid A and butylene glycol (BLG) as liquid B of the binary mixture. The time domain reflectometry (TDR) [1] in reflection mode has been used to obtain the dielectric parameters. The objective of this article is to report the dielectric parameter study of FMD-BLG binary mixture by using TDR technique in the temperature range 20 C-40 C. Amides and glycols have attracted the attention of a number of researchers [2][3][4][5][6][7] in different fields because of high dielectric permittivity and biological applications.…”

To cite this article: V.V. Navarkhele & M.K. Bhanarkar (2010) High-frequency dielectric response of the binary mixture formamide-butylene glycol, Dielectric relaxation study of formamide (FMD) has been carried out with butylene glycol (BLG) at different temperatures. Time domain reflectometry in reflection mode has been used to measure the reflection coefficient in the frequency range of 10 MHz-20 GHz. The dielectric parameters, that is, static dielectric permittivity (2 0 ) and relaxation time () have been obtained by Fourier, transform and least square fit methods. The experimental results show non-linear variation in dielectric permittivity and relaxation time with volume fraction of BLG, confirm the structural formation due to the intermolecular interaction between FMD and glycol. The variation in excess permittivity (" E ), excess inverse relaxation times (1/) E , Kirkwood correlation factors (g eff , g f ), activation enthalpy (ÁH) and entropy (ÁS) for the binary mixtures have also been reported in this article. IntroductionThe dielectric relaxation study of solute-solvent mixture at microwave frequency gives information about formation of monomers and multimers. It gives understanding of solute-solvent interaction and liquid structure. In this experimental study, formamide (FMD) is considered as liquid A and butylene glycol (BLG) as liquid B of the binary mixture. The time domain reflectometry (TDR) [1] in reflection mode has been used to obtain the dielectric parameters. The objective of this article is to report the dielectric parameter study of FMD-BLG binary mixture by using TDR technique in the temperature range 20 C-40 C. Amides and glycols have attracted the attention of a number of researchers [2][3][4][5][6][7] in different fields because of high dielectric permittivity and biological applications. The amide represents an important class of organic solvent due to high polarity, strong solventing power and large liquid state range.
