Molecular interactions of Pyridinium DIL with D–glucose: Volumetric, acoustic and viscometric approach

Abstract

Apparent molar volume, apparent molar isentropic compressibility along with Jones–Dole viscosity coefficients of [1–(3–(1–methyl–1H–imidazol–3–ium–3–yl) propyl) pyridin–1–ium bromide] or ([Py–mim–Br2]) in D–glucose–water solutions were determined from density, speed of sound and absolute viscosities measurements. The transfer values of apparent molar volume(ΔtrVϕ0) and apparent molar compressibility (Δtrκϕ0) are positive and increases with rise in studied concentration range. Thermal expansion coefficient(α∗) and hydration number(nh) are rises with increase in the concentration of D–glucose. The results have been estimated on the basis of ion–ion, ion–solvent interactions.
