Abstract

Densities were determined for binary mixtures containing the protic ionic liquids: bis (2-hydroxyethyl) ammonium acetate, propionate, and butanoate ([BHEA][Ac], [BHEA][Pr], and [BHEA][Bu]) and water at six different temperatures (293.15, 303.15, 313.15, 323.15; 333.15, 343.15 K) and atmospheric pressure. The densities were fitted using the Mattedi-Tavares-Castier equation of state, which correlated the experimental data well. For the system bis (2-hydroxyethyl) ammonium butyrate + water, a maximum in density was observed at intermediate compositions, at each of the measured temperatures. The excess molar volumes were generally negative for the three binary systems studied, except for certain compositions at the highest measured temperatures.
