Solution behaviour prevailing in 1, 3-dimethylimidazoliummethylsulfate (IL) and some diverse industrially important alkoxy-alcohols or cellosolves have been investigated by electrolytic conductivity, density (⍴), viscosity (η) and FT-IR spectroscopic investigation. The derived parameters such as the limiting molar conductivities (Λ₀), association constants (K_A), the distance of closest approach (R), etc. of the ions supplemented with conductance, density and viscosity have been evaluated using the Fuoss conductance equation. The quantitative values of molecular interactions from thermodynamic parameters have been discussed in terms of some non-covalent interactions. Functional groups of the pure solvents and structural characteristics of ionic liquid in different solvents have been discussed and taken into contemplation for spectroscopic study.
