%X Densities were determined for binary mixtures containing the protic ionic liquid bis(2-hydroxyethyl)ammonium acetate BHEAA and an alcohol (methanol, ethanol, and 1-propanol) at four different temperatures (293.15, 303.15, 313.15, and 323.15) K and ambient pressure. Coefficients of thermal expansion and excess molar volumes were calculated from the experimental densities. The excess molar volumes were fitted using the Redlich-Kister polynomial equation. Negative deviations from ideal behavior of the excess molar volume were observed for all systems investigated in this study. The results were interpreted in terms of ion-dipole interactions and structural factors of the ionic liquid and alcohol. It was observed that an increase of the alcohol carbon chain length led to lower interactions on mixing. © 2011 Springer Science+Business Media, LLC. %D 2011 %N 3 %R 10.1007/s10953-011-9658-6 %O cited By 48 %L scholars2231 %J Journal of Solution Chemistry %T Density and excess molar volume of the protic ionic liquid bis(2-hydroxyethyl)ammonium acetate with alcohols %A K.A.
