Karazin popup.description2 Objects of investigation: Et4NBF4 solutions in propylene carbonate, Еt4NBF4 and Bu4NBF4 in acetonitrile and NiCl2 in dimethyl sulphoxide.The aim of this work is determination of quantitative characteristics of interparticle interactions and influence of temperature, concentration and molecular properties of components on them.Methods of investigation: conductometry, NMR, quasielastic neutron scattering.From conductance data limiting molar conductivities and association constants were determined for Еt4NBF4 in propylene carbonate at 5 - 125 °С and for Еt4NBF4 and Bu4NBF4 in acetonitrile at 25 - 55 °С.It was established, that quasilattice model of electric conductivity describes solutions of Еt4NBF4 and Bu4NBF4 in acetonitrile up to 0.1 mol/dm3. For bigger concentrations it is necessary to take in to account ionic association. Mean diffusion coefficients of solvent molecules were determined for NiCl2 solutions in methanol of molality 0.12 and 0.53 mol/kg by using quasielastic neutron scattering technique. It was shown, that Ni2+ ions govern solvent molecules dynamics not only in solvation shells but also in bulk solvent. Product Description popup.authors popup.nrat_date 2020-04-02 Close
