Abstract

Densities and refractive indices have been measured for binary mixtures of 1-propyronitrile-3-hexylimidazolium bromide + ethanol in the temperature range 293.15– 323.15 K. From the experimental data the excess molar volume V E, refractive index deviation �nD, and the coefficient of thermal expansion α were calculated and fitted to fifth- and third-order Redlich–Kister type equations, respectively. Using the measured densities, the apparent molar volumes (Vφ), limiting apparent molar volumes (V 0 φ ) and limiting apparent molar expansivities (E0 φ) were also determined and the details are discussed.
