摘要：

Electrolytic conductivity, density, viscosity and FTIR study of an ionic liquid, 1-butyl-4-methylpyridinium hexafluorophosphate ([bmpy]PF6) have been measured in diverse industrially significant solvents viz. acetonitrile, tetrahydrofuran and 1,3 dioxolane at various temperatures. In acetonitrile, the ion-pair formation of the IL was analyzed by Fuoss conductance equation. In Tetrahydrofuran and 1,3 Dioxolane systems, triple-ion formation analyzed by the Fuoss-Kraus theory. Ion-solvent interactions have been inferred in terms of limiting apparent molal volumes and viscosity B-coefficients. The results obtained from the experimental study, have been conferred in terms of ion-dipole interactions, structural aspect, configurational theory and solvatochromic effect. (C) 2016 Elsevier B.V.
