ABSTRACT

Densities of ternary some Schiff bases N,N'-salicylidenephenylediamine (salophen), N,N'- 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, transfer partial molar volume, partial molar expansion, and Hepler's constant 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.
