Despite the growing popularity of ionic liquids (ILs) as attractive solvents with various interesting properties, the lack of low-uncertainty thermodynamic data persists for many of these compounds. Even for commonly available ILs, crucial parameters such as melting temperatures and fusion enthalpies are often unknown or remain burdened with significant uncertainties. Therefore, this study focuses on a thorough characterization of the phase behavior for eight ionic liquids containing the 1-butylpyridinium cation by means of differential scanning calorimetry and variable temperature X-ray powder d iffraction. In addition to phase behavior studies, the heat capacities of the ILs were determined using a Tian-Calvet-type calorimeter. For many of the compounds studied, the presented data are the first of their kind.
