Sažetak
Volumetric properties (apparent molar volume, standard partial molar volumes, apparent molar volume at infinite dilution, limiting apparent molar expansibilities and Heppler's coefficient) of 1-methylimidazolium acetate, (C0mim)(Ac) ionic liquid binary mixtures with two polar aprotic amides: N, N-dimethylacetamide (DMA), and N, N- dimethylformamide (DMF), and one polar aprotic organosulfur and environmentally-friendly solvent: dimethyl sulfoxide (DMSO), are calculated from the experimental densities and reported in the temperature range from (278.15 to 313.15) K in DMA and DMF or (293.15 to 318.15) K in DMSO at atmospheric pressure (0.1 MPa) and in the molality range from (0.0050 to 0.1000) mol kg–1, respectively. The validity of Masson's equation was checked and applied to describe the apparent molar volume dependence on molarity. The apparent molar volume at infinite dilution and interaction coefficient were obtained from this dependence at each temperature. Finally, structure-maker or structure-breaker properties of investigated ionic liquid in various solvents are discussed.
