Abstractt

Densities of ternary mixtures of some Schiff bases N,N鈥?salicylidenephenylediamine (Salophen), N,N鈥?em>-bis(salicylaldehyde)-1,3-diaminopropane (Salpr), N,N-bis(salicylidene)-1,2-cyclohexadiamine (Salcn) + ionic liquid, 1-penthyl-3-methylimidazolium bromide ([PnMIm]Br) + N,N-dimethylformamide have been measured at (308.15, 318.15 and 328.15) K. These data have been used to calculate apparent molar volume, , the standard partial molar volume, , standard partial molar volume of transfer, , standard partial molar isobaric expansion, and isobaric thermal expansion coefficient (伪) for the mixtures studied. All these parameters were used to interpret the effect of ionic liquid on the solute-solvent interactions and solvation behavior occurring between ionic liquid and Schiff bases in these ternary mixtures.
