摘要
In this contribution, dynamic viscosities, densities, and speeds of sound of 1-ethyl-3-methylimidazolium ethyl sulfate (EMISE) with methanol, 1-propanol, and 2-propanol at T = (298.15, 313.15, and 328.15) K and refractive indices at T = 298.15 K and at atmospheric pressure have been measured over the whole composition range. Excess molar volumes, excess molar isentropic compressions, and viscosity deviations for the binary systems from T = 298.15 K to T = 328.15 K and refractive deviations at 298.15 K have been calculated and were satisfactorily fitted to a Redlich-Kister equation to give the fitting parameters and the root-mean-square deviations.
