Influence of d-glucose on solvation behavior of Bis C3 (mim) Br2

Abstract

In this work, experimental densities (ρ), speeds of sound (u) and relative viscosities (ηr) of DIL i.e. 1, 1-(propane-1, 3-diyl)-bis (3-methyl-1H-imidazolium-1-yl) dibromide or Bis C3 (mim) Br2 in aqueous solution 0.1molkg−1 of d-glucose as a function of concentration have been measured at T/K=(293.15, 298.15, 303.15, 308.15 and 313.15). From these experimental data, thermodynamic and transport functions such as apparent molar volume (Vϕ) of solute, limiting apparent molar volume of solute (Vϕ0), isentropic compressibility(κs), apparent molar isentropic compressibility (κϕ) of solute, limiting apparent molar compressibility of solute (κϕ0), limiting apparent molar expansivity (Eϕ0) of solute, thermal expansion coefficient(α∗), Jones-Dole viscosity coefficientsA, Β, D variation of viscosity Βcoefficient with temperature i.e. dΒ/dT, hydration number of DIL in water and in aqueous solutions of d-glucose have been calculated. Transfer volumesΔtrVϕ0 and transfer compressibilities Δtrκϕ0 of DIL from water to aqueous solutions of d-glucose at different temperatures have also been obtained. The results obtained have been interpreted in terms of various interactions taking place among solute and solvent molecules.
