ABSTRACT

The thermal conductivities of 1-ethyl-3-methylimidazol-3-ium ethylsulfate, 1-ethyl-3-methylimidazol-3-ium ethylsulfate + ethanol, 1-ethyl-3-methylimidazol-3-ium ethylsulfate + water, and 1-ethyl-3-methylimidazol-3-ium ethylsulfate + ethanol + water were reported. The measurements were performed in the temperature range from (283.15 to 343.15) K by a transient hot-wire technique covering the whole composition range at atmospheric pressure. The uncertainty of experimental thermal conductivity is 2.0 % with a coverage factor of k = 2. The second-order Scheffe polynomial was used to correlate the temperature and composition dependence of the experimental thermal conductivities for both binary and ternary mixtures. The average absolute deviation of those calculated values from the experimental data was 0.64 %.
