ABSTRACT

Thermodynamic properties of N,N0-salicylidenephenylediamine Schiff base (Salophen) in the solutions of ionic liquid, 1-butyl-3-methylimidazolium bromide ([BMIm]Br) + organic solvents (N,N-dimethylacetamide DMA, and dimethylsulfoxide DMSO) have been measured at 298.15 K. The measured density and viscosity values have been used to calculate apparent molar volumes, V/, standard partial molar volumes, V0 /, standard partial molar volumes of transfer, DtrV0 /, viscosity B-coefficients, and solvation numbers, B=V0 /, for the solutions being studied. All of these parameters were used to interpret the solute solvent interactions and solvation process occurring between ionic liquid and Salophen.
