The thermophysical properties, densities, p, speeds of sound, u and dynamic viscosities, eta of pure ionic liquid, 1-ethy1-3-methylimidazolium ethylsulfate, ([EMIM][ES]), and solvents 1-butanol, methanol and of their binary and ternary mixtures have been measured experimentally at a temperature range from (298.15-323.15) K, with an interval of 5 K and at pressure 0.1 MPa by using Anton Paar vibrating tube density and sound velocity meter DSA 5000M and Lovis microviscometer 2000M. The excess molar volumes, V-E, isentropic compressibilities, its, molar isentropic compressibilities, K-s,K-m,K- excess molar isentropic compressibility,K-E (s,m') and viscosity deviations Delta eta have been calculated using the experimental p, u and eta data at the same temperature range and pressure for IEMIK[ES] 1-butanolimethanol binary systems and the VE, Ks, excess isentropic compressibility, its and Delta eta for ternary [EMIM]IES] + 1butanol + methanol system. The V-E, K-s(E), K-E,(s,m) and Delta eta data for the studied binary/ternary systems have been fitted to Redlich-Kister equation. The variations in (V,Ks,E)-K-E K-S,M(E) Delta eta and Al values with changes in composition and temperature have been discussed in terms of hydrogen bonding, ion dipole interactions and structural effects on mixing of ILs and solvents.
