Physical Properties of Binary Mixtures of the Ionic Liquid 1-Methyl-3-octylimidazolium Chloride with Methanol, Ethanol, and 1-Propanol at <i>T</i> = (298.15, 313.15, and 328.15) K and at <i>P</i> = 0.1 MPa

Abstract

In this work, dynamic viscosities, densities, and speed of sound of 1-methyl-3-octylimidazolium chloride, [C8mim][Cl], with methanol, ethanol, and 1-propanol at T = (298.15, 313.15, and 328.15) K and refractive index at T = 298.15 K and P = 0.1 MPa have been measured over the whole composition range. Excess molar volumes, isentropic compressibility deviations, and viscosity deviations for the binary systems from T = (298.15 to 328.15) K were calculated. These results were fitted to a Redlich−Kister equation to determine the fitting parameters and the root mean square deviations.
