ABSTRACT

Volumetric properties of 1-butyl-3-methylimidazolium tris(pentafluoroethyl)trifluorophosphate ([BMIM][FAP]) ionic liquid binary mixtures with two protic amides: N-methyl-formamide (NMF) and N-ethylformamide (NEF), and three aprotic amides: N,N-dimethylformamide (DMF), N,N-dibutylformamide (DBF), and N,N-dimethylacetamide (DMA), are calculated from the experimental densities and reported in the temperature range from (293.15 to 323.15) K and at atmospheric pressure (0.1 MPa) over the whole composition range. The excess molar volumes have positive values in the whole concentration range, with maximum values in the range between 0.3 and 0.6 ionic liquid mole fraction. Higher values of excess molar volumes are observed in the mixtures containing aprotic amides (DMF, DBF, DMA). Also, the molar volume of binary mixtures, the apparent molar volumes, the partial molar volumes of the components, and the partial molar volumes of the components at infinite dilution are calculated. All of the results are compared with those obtained for pyrrolidinium-based ionic liquids with the same anion in the mixtures with the selected amides.
