Activity coefficients at infinite dilution measurements for organic solutes in the ionic liquid 1-butyl-3-methyl-imidazolium 2-(2-methoxyethoxy) ethyl sulfate using g.l.c. at TÂ =Â (298.15, 303.15, and 308.15)Â K

The partial molar excess enthalpies at infinite dilution values, ΔH1E∞, were calculated from the experimental γ13∞ values obtained over the temperature range.
