Dielectric studies of binary mixtures of ethylene glycol mono phenyl ether with 1-butanol at different temperatures

Abstract

Static permittivity ([Formula: see text]), refractive index ([Formula: see text]) and density ([Formula: see text]) of binary mixtures of ethylene glycol mono phenyl ether (EGMPE) with 1-butanol (1-BuOH) over the entire range of mole fraction and at temperatures ([Formula: see text], 313.15 and 323.15[Formula: see text]K) have been measured. From the experimental data, parameters such as excess static permittivity ([Formula: see text]), excess permittivity at optical frequency ([Formula: see text]), effective Kirkwood correlation factor ([Formula: see text]), corrective Kirkwood correlation factor ([Formula: see text]) and Bruggeman factor ([Formula: see text]) have been calculated to obtain qualitative and quantitative information about the complex formation through H-bond in binary system. In order to predict the static permittivity of polar–polar binary mixtures six mixing rules were applied and for refractive index five mixing rule were applied. Experimental results of permittivity ([Formula: see text]) and refractive index (n) are compared with those obtained from theoretical calculations. Excess parameters were fitted to the Redlich–Kister type polynomial equation.
