ABSTRACT

The densities and viscosities of the ternary solutions [NCyP][p-TSA] (1-cyclohexyl-2-pyrrolidinone p-toluenesulfonate) + [NCyP][BSA] (1-cyclohexyl-2-pyrrolidinone benzenesulfonate) + H2O and [NMP][p-TSA] (1-methyl-2-pyrrolidinone p-toluenesulfonate) + [NMP][BSA] (1-methyl-2-pyrrolidinone benzenesulfonate) + H2O and their binary subsystems at (298.15, 303.15, and 308.15) K and atmospheric pressure were measured. The simple equations developed for mixed electrolyte solutions have been invoked to predict the densities and viscosities for these ionic liquid solutions. The predicted values agree well with the experimental data, indicating that the examined properties of the ternary aqueous solutions of pyrrolidone-based ILs can be well predicted from the corresponding data of their binary subsystems of equal ionic strength using simple equations.
