Conformational Equilibrium and its Influence on the Dielectric and Thermodynamic Behaviour of Cyclohexane, or Benzene + 1,2‐Dibromoethane

Static permittivities (ϵ), excess enthalpies (HE), and excess volumes (VE) of Cyclohexane or Benzene + 1,2-Dibromoethane, and the densities and refractive indices of the pure components, at 288.15, 298.15, 308.15 and 308.15 K, were measured. The dielectric measurements allowed the study of the conformational equilibrium and the calculation of the equilibrium constant and the conformational enthalpy. We have found that HE is practically independent of T in the range studied by us, and an explanation of this result is proposed. The influence of the temperature on VE is small and negative. HE and VE data were correlated in terms of Flory-Patterson's theory.
