Association of n-alcohols in non-polar solvents. Part I. The dielectric polarisations, apparent dipole moments, and near-infrared spectra of n-alcohols in carbon tetrachloride and cyclohexane

Abstract

Dielectric constant, ε, density, and near-infrared spectra of a series of solutions of graded concentration of n-alcohols in carbon tetrachloride and cyclohexane have been determined. Apparent dipole moments of the solutes have been calculated and solute polarisation, P₂, evaluated as a function of alcohol weight fraction. Existence in solution of monomer only coincides with linear dependence of both ε and P₂ on alcohol weight fraction. Positive and negative deviations of ε and P₂ are explained by presence of effective amounts of linear dimer and trimer, and cyclic polymer, respectively.
