Abstract


In this work density data for binary mixtures of the ionic liquid 1-ethyl-3-methylimidazolium ethylsulfate ([EMIM][EtSO(4)]) with acetone, acetonitrile, propylene carbonate, dichloromethane, methanol, ethanol, and water are presented. Measurements were performed in dependence on composition for temperatures from (278.15 to 308.15) K using the vibrating-tube method with an expanded relative uncertainty (k = 2) of less than +/- 0.02 %. All calculated excess molar volumes are negative, indicating denser molecular packing than in the pure liquids. The size and the structure of the solvent molecules as well as the nature of interaction between all mixture components seem to affect the extent of the observed compression effect.
