Study of Molecular Interaction in Binary Mixtures (1-Propanol + Acetophenone)

Abstract:

Studies on Physico-chemical properties of binary liquid mixtures provide information on the nature of interactions between the constituent of the binaries. Literature provides extensive data on the static dielectric constant (ε₀) and refractive index (n) of liquid compounds, but the combined study of all is quite scarce. In the present work static dielectric constant (ε₀) and refractive index (n) have been experimentally determined for binary liquid mixture of 1-Propanol (PrOH) with Acetophenone (ACP) over the entire concentration range of mixture composition (0.0 →1.0) at constant temperature 303 K. Static dielectric constant (ε₀) and refractive index (n) for the binary mixture have been measured using high precision LCR meter (0.2 MHz) and Abbe’s refractometer respectively. Excess of static dielectric constant (ε₀)^E and refractive index (n)^E are determined and fitted with Redlich-Kister polynomial equation to derive the binary coefficients and standard deviations. For interaction and structural information various parameters namely, Kirkwood correlation factor (g), Kirkwood effective correlation factor (g^eff), Kirkwood angular correlation factor (g_F) and Bruggeman parameter (f_B) are determined for the binary mixtures. Variations of these parameters against the concentration of constituents are discussed in terms of molecular interaction between the constituent species.
