Abstract
The quasi-chemical model of nonideal associated solutions was for the first time used to construct a model of solutions of polar substances whose supramolecular structure contained chain and star-like aggregates with an arbitrary number of beams as the main fragments. Analytic methods for calculating the concentrations of aggregates and integral (the mean aggregation numbers) and differential (aggregate distribution functions according to topological types, composition, size, etc.) characteristics of the supramolecular organization of solutions were developed. Equations for the dipole moments of aggregates and dipole correlation factors of solution components were obtained. These equations were used to establish interrelations between the permittivity of a solution and its excess thermodynamic functions on the one hand and the thermodynamic and structural parameters of its supramolecular organization on the other.
