Annotation	This paper is a continuation of a study focused on thermodynamic properties of isomeric andquasi-isomeric ionic liquids. In this work 5 novel ionic liquids were synthesized, namely 1-(2-(2-ethoxyethoxy)ethyl)-3-alkylimidazolium bis(trifluoromethylsulfonyl)imides, where alkyl stands for different C5sub-stituents. These species were characterized as to their isobaric molar heat capacity and thermal stability.The results are discussed with respect to different substituent isomerism and compared with data fromour previous work (Rotrekl, Fluid Phase Equilib. 2017) that reported on a similar group of isomeric ionicliquids, namely 1-butyl-3-alkylimidazolium bis(trifluoromethylsulfonyl)imides. Data analysis of theexperimental heat capacites was carried out using a non-statistical approach of the mathematicalgnostics. The conclusions drawn from the present work bring an insight into thefine structure-propertyrelationship which is useful in the development of predictive tools as well as it direct applications such asin energy storage or thermalfluids development.
