Dielectric study of molecular association in the binary mixtures (2-ethyl-1-hexanol + alcohol) and (cyclohexane + alcohol) at 298.2 K

Experimental results of dielectric investigations of three binary mixtures (ethanol + 2-ethyl-1-hexanol), (n-butanol + 2-ethyl-1-hexanol), and (tert-butanol + 2-ethyl-1-hexanol) were reported for various mole fractions at 298.2 K. The variations of dipole moment and correlation factor, g, with mole fraction in these mixtures were investigated using a unified quasichemical method described by Durov. The molecular associations of (ethanol + cyclohexane), (n-butanol + cyclohexane), and (tert-butanol + cyclohexane) binary mixtures were also investigated using the static dielectric method. A similar trend was observed in the variation of the dipole moments with the solute mole fractions in the both binary systems (i.e., alcohol + 2-ethyl-1-hexanol and alcohol + cyclohexane).
