摘要

Abstract

The densities

conductivities

and viscosities were measured for ternary solutions of N-hexyl

methylpyrrolidinium bromide ([PP

]

Br)-N-butyl

methylpyrrolidinium bromide ([PP

]

Br)-H

O and its binary subsystems [PP

]

Br-H

O and [PP

]

Br-H

O at (298.15

303.15

308.15

and 313.15) K

respectively. The results were used to test the predictability of the simple equations established for the prediction of density

conductivity

and viscosity of the mixed electrolyte solutions. The results show that the examined simple equations can offer good predictions for density

conductivity

and viscosity of the mixed ionic liquid solutions in terms of the corresponding properties of its binary subsystems of equal ionic strength.
