Complex Dielectric spectra of Methyl acetate (MA) with 2-Alkoxyethanols like 2-methoxyethanol (2-ME), 2-ethoxyethanol (2-EE), 2-butoxyethanol (2-BE) for various concentrations over the frequency ranges from 10MHz to 20GHz at 308.15K were recorded using Time Domain Reflectometry (TDR). The dielectric constant, dielectric permittvity and dielectric loss were obtained from the TDR measurement. The molecular interaction parameters like relaxation time, Kirkwood correlation factors, Bruggeman factor, excess dielectric constant, excess inverse relaxation time and excess Helmholtz free energy of activation were also calculated. This study gives the information about the nature of molecular interaction between the participating liquid molecules.

“…Additionally, its flexibility (in terms of adaptability to the desired application) has contributed to making TDR an interesting solution for the most diverse applications, such as fault detection on electric wires [20,21]; qualitative and quantitative control of liquids [22][23][24]; moisture measurements of soil [25][26][27][28] and of porous materials in general [29]; dielectric characterizations of materials [30][31][32][33]; and structural analysis [34][35][36].…”

“…Amides are characterised by large dielectric constant mainly due to its own dipole and partly due to interactions with surrounding molecules [2][3][4]. Interactions between the constituent molecules and response of binary mixtures to static low frequency electric field can be estimated from the magnitude of dielectric constant of mixture [3,[5][6][7][8]. Most of the knowledge pertaining to kinematics, the molecular interactions and industrial applications of liquid mixtures can be assessed through information about dielectric properties of binary liquid mixtures [9][10][11][12][13][14][15][16][17].…”

Certain polar amides(v) are dissolved in benzene, a nonpolar solvent(u) to prepare binary mixtures with different composition of the amides like acetanilide, N-N-dimethyl acetamide, N-methyl acetamide, acetamide and formamide. Static relative permittivity ɛ0uv , high frequency permittivity ɛ ∞uv for different weight fraction of polar solute at 30°C are determined. The dielectric behaviour of binary mixtures are investigated under electric field of low frequency by using the Debye model for polar liquids. Static dipole moment µs , dipole moment µv from conductivity measurements and µ t from bond angle and bond moment measurements are computed. The dipole moments are consequence of attractive interaction between the adjacent molecules in binary mixture due to variation of electron densities. Hydrogen bonding, associated charge distribution among the constituent molecules, changes in bond angle values are some of the factors that give rise to dipole moment of binary mixtures. Nearly equal and close values of µs , µv and µt proves the correctness of dielectric behaviour studies of amides- benzene binary mixtures.
