Vaporization and formation enthalpies of 1-alkyl-3-methylimidazolium tricyanomethanides

Thermochemical studies of the ionic liquids 1-ethyl-3-methylimidazolium tricyanomethanide [C2MIM][C(CN)3] and 1-butyl-3- methylimidazolium tricyanomethanide [C4MIM][C(CN)3] have been performed in this work. Vaporization enthalpies have been obtained using a recently developed quartz crystal microbalance (QCM) technique. The molar enthalpies of formation of these ionic liquids in the liquid state were measured by means of combustion calorimetry. A combination of the results obtained from QCM and combustion calorimetry lead to values of gaseous molar enthalpies of formation of [CnMIM][C(CN)3]. First-principles calculations of the enthalpies of formation in the gaseous phase for the ionic liquids [CnMIM][C(CN)3] have been performed using the CBS-QB3 and G3MP2 theory and have been compared with the experimental data. Furthermore, experimental results of enthalpies of formation of imidazolium-based ionic liquids with the cation [CnMIM] (where n = 2 and 4) and anions [N(CN)2], [NO3], and [C(CN)3] available in the literature have been collected and checked for consistency using a group additivity procedure. It has been found that the enthalpies of formation of these ionic liquids roughly obey group additivity rules.
