Dielectric studies of binary mixtures of polar liquids in non-polar solvents-Excess correlation factor and excess free energy of mixing

Abstract

A study. of the dielectric properties of binary mixture of polar liquids, namely. n-butanol, n-butanol, t-butanol in non-polar solvents such as benzene. tetrachloromethane and n-heptane has been made Two new parameters, excess correlation factor (og) and excess free energy (/j,Fn) have been evaluated. These parameters 'have been used to throw light on the dynamic characteristics of molecular association in these binary mixtures of polar-non-polar liquids.
