Resumo
Enthalpies of solution of 1-butyl-3-methylimidazolium tetrafluoroborate, [BMIm]BF4, are reported at 298.15K in a set of 15 hydrogen bond donor and hydrogen bond acceptor solvents, chosen by their diversity,namely, water, methanol, ethanol, 1,2-ethanediol, 2-choroethanol, 2-methoxyethanol, formamide, propylenecarbonate, nitromethane, acetonitrile, dimethyl sulfoxide, acetone,N,N-dimethylformamide,N,N-dimethyl-acetamide, and aniline. These values are shown to be largely independent of [BMIm]BF4 concentration.The obtained enthalpies of solution vary from very endothermic to quite exothermic, thus showing a very high sensitivity of the enthalpies of solution of [BMIm]BF4 to solvent properties. Solvent effects on the solution process of this IL are analyzed by a quantitative structure-property relationship methodology,using the TAKA equation and a modified equation, which significantly improves the model’s predictive ability. The observed differences in the enthalpies of solution are rationalized in terms of the solvent properties found to be relevant, that is,π* and ETN.
