Density and excess molar volume of binary mixture of thiocyanate-based ionic liquids and methanol at temperatures 293.15-323.15Â K

Partial molar volumes at infinite dilutions (Vm,i∞) of the ILs and methanol were determined from the Redlich-Kister coefficients. For all the studied systems, the VmE is negative over the entire composition range. The VmE and Vm,i∞ are interpreted in terms of intermolecular interactions in the binary mixture. Density functional theory has been used to investigate the interactions between methanol and the studied ILs.
