Abstract
The density, velocity of ultrasound, and the degree of depolarization and intensity of molecular light scattering were measured for chlorobenzene-o-chlorotoluene solutions. The excess molar volume, adiabatic compressibility, and isotropic and anisotropic molecular light scattering intensities were calculated. An analysis of the concentration dependences of the calculated parameters showed that solutions contained homo-and heteromolecular agglomerates of similar sizes over the range of chlorobenzene concentrations 0.1 < x < 0.9. The intermolecular interaction energy between like molecules was higher somewhat than that between unlike molecules. At low chlorobenzene concentrations in o-chlorotoluene (x < 0.1), the thermodynamic and molecular light scattering parameters sharply changed, which was evidence of substantial changes in the local structure of o-chlorotoluene caused by the addition of chlorobenzene.
