Apparent Molar (Volumetric/Compressibility) and Transport Properties of d-Maltose-1-Butyl-3-methylimidazolium Hexafluorophosphate—Water Ternary Systems at Different Temperatures

Densities, speeds of sound and viscosities of different molalities of d-maltose in aqueous solutions of an ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate, have been measured, for temperature steps of 5 K, from 293.15 to 313.15 K at atmospheric pressure. From the experimental data, apparent molar volumes, limiting apparent molar volumes, apparent molar compressibilities, limiting apparent molar compressibilities, transfer volumes and compressibilities, limiting apparent molar expansibilities, thermal expansion coefficients, relative viscosities and Jones–Dole B-coefficients have been estimated. The results have been examined in terms of hydrophobic–ionic and hydrophilic–ionic interactions. It is observed that strong solute–solvent interactions exist in the ternary system which increase with increasing ionic liquid concentration.
