文摘

The speed of sound and density of mixtures of 1-ethyl-3-methylimidazolium trifluoromethanesulfonate ([emim][triflate]) with methanol, ethanol, 1-propanol, and water, as well as of the pure components have been experimentallymeasured over the whole range of compositions at T = (278.15 to 338.15) K and atmospheric pressure. Fromthese experimental data, the excess molar volume, excess isentropic compressibility, and excess speed of soundhave been calculated and fitted to an extended version of the Redlich-Kister equation, which takes into accountthe dependence on composition and temperature simultaneously. The Prigogine-Flory-Patterson theory has alsobeen used to explain the behavior of these systems.
