Non-linear dielectric study of dipolar association of nitrocyclohexane in cyclohexane

Abstract

The non-linear dielectric effect (n.d.e.) has been studied for nitrocyclohexane in cyclohexane and the correlation factors R_p and R_s determined. Assuming the simplest process of dipole association, i.e. dimerization, the molar fractions of dimers x₂ and monomers x₁, as well as the dipole moment µ_dim of the dimers, are calculated. The equilibrium constant, K_x, and free enthalpy, ΔG, of the dimerization process and the structure of the dimer are determined.
