The volumetric and dielectric behaviour of acetic acid in mixtures with nonpolar liquids

Abstract

Results for the volume change of mixing of acetic acid with carbon tetrachloride, benzene, and cyclohexane are given. Further, the dielectric constant has been determined for acetic acid in carbon tetrachloride from spectroscopic measurements of the association equilibrium. The volume changes are both positive and large. The dielectric behaviour of acetic acid in carbon tetrachloride parallels that of acetic acid in benzene and n-heptane previously reported. Our results taken together with published data indicate: (i) the dipole moment of acetic acid monomer in the gas phase is higher than has been previously reported, (ii) the dipole moment of acetic acid monomer in solutions rich in acetic acid is considerably greater than in the gas phase, possibly because of a contribution of the trans-configuration, and (iii) a strong attractive interaction exists between acetic acid monomer and acetic acid dimer.
