Physical and excess properties of (methyl acetate + methanol + 1-octyl-3-methyl-imidazolium bis(trifluoromethylsulfonyl)imide) and its binary mixtures at T = 298.15 K and atmospheric pressure

Densities, dynamic viscosities, and refractive indices of the ternary system composed by methanol, methyl acetate, and 1-octyl-3-methyl-imidazolium bis(trifluoromethylsulfonyl)imide and the binary combinations of these constituents have been measured. The excess molar volumes as well as molar refraction and viscosity changes of mixing were calculated and fitted to the Redlich–Kister equation to determine the fitting parameters and the root-mean-square deviations.
