摘要：

The excess molar enthalpies, , data of ternary 1-ethyl-3-methylimidazolium tetrafluoroborate (1) + pyrrolidin-2-one or 1-methyl pyrrolidin-2-one (2) + cyclopentanone or cyclohexanone (3) mixtures have been measured at 298.15 K and 0.1 M Pa using microdifferential scanning calorimeter. The values of [emim][BF4] (1) + 2-Py (2) + cyclopentanone or cyclohexanone (3) are endothermic, while those for [emim][BF4] (1) + NMP (2) + cyclopentanone or cyclohexanone (3) mixtures are negative over entire composition of x (1) and x (2). The observed data of have been investigated in terms of Graph and Prigogine-Flory-Patterson theories. The results indicate that values estimated by Graph theory compare well with experimental values.
