Supramolecular Organization and Physico-chemical Properties of Liquid Systems. Cyclohexanone-Cyclohexanol Mixture

Russian J.Phys.Chem., accepted for publication, translated to English from Zh.Fiz.Khim.

ABSTRACT. Supramolecular organization in cyclohexanone - cyclohexanol mixture was studied in a wide temperature and a whole concentration intervals. Equations for calculating of static permittivity (dipole correlation factor), excess functions of mixing (Gibbs energy, enthalpy, entropy), and activity coefficients of components have been derived. A model implying the formation of alhohol's chains of arbitrary length with correlated states of H-bonds in associates (collective H-bonds), solvated by polar ketoneнs molecules was grounded. The thermodynamic and structural characteristics of the supramolecular aggregation was obtained. An unified description of molecular nature of dielectric as well as thermodynamic properties of cyclohexanone - cyclohexanol mixture (model of a polar associating substance in a polar solvating solvent) in terms of generalized quasi-chemical models on the molecular-structural level was demonstrated.
