The object: The structure and dynamical aspects of interparticles interactions in aprotic solvents. The aim: development of model-conceptual ideas on dynamics of interparticle interactions and structure of electrolytes solutions from experimental found rules of temperature, ion and solvent nature influence on quantitative solvation characteristics of particle in aprotic solvents. The methods: viscosimetry, densimetry. The results: The method of viscosimetry data processing which takes into account the processes of ionic association has been developed. The efficiency of the method has been shown with use of own experimental data on viscosity and density of NaCl, NaBr, NaBPh4, Bu4NBr, CaCl2, NiCl2 and CdCl2 solutions in DMSO into the temperature range 25 - 70(С. In the frame of the developed conception of dynamics of ionic solvation the dependence of its quantitative characteristics on the temperature, nature of ions and solvents has been analysed. As the result four groups of ions have been revealed: la rge organic ions, monoatomic anions, one- and twocharged cations of s-elements and twocharged cations of d-elements. It has been first ascertained that ion aggregate inherits from composing this aggregate ions the nature and intensity of theirs influence on the dynamic properties of solvent molecules. The field: physical-chemical researches, electrochemistry, chemical technology, professional education.
