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

Dielectric constant, Iµ, 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 Iµ and P2 on alcohol weight fraction. Positive and negative deviations of Iµ and P2 are explained by presence of effective amounts of linear dimer and trimer, and cyclic polymer, respectively.
