Heat capacity of 1-hexadecyl-3-methylimidazolium based ionic liquids in solid and liquid phase
Original language description
In this work, two ionic liquids with a 1-hexadecyl-3-methylimidazolium cation were synthesized with differentanions. Chloride and saccharinate, respectively, both of them showing melting points above room temperature,ranging between (324.15 and 338.15) K and enthalpies of fusion close to or higher than 100 J/g, making them po-tentially suitable phase-change materials (PCMs) for latent heat storage. This application potential can be en-hanced by a suitably large heat capacity and thermal conductivity of the material both in the liquid and solidphase. Heat capacity was therefore measured in this work as a function of temperature using the differentialscanning calorimetry (DSC) to determine how it is affected by the anion structure. Care has been taken to eval-uate the influence of the phase change on the measured data. The experimental data have then been analyzed bymeans of methods based on mathematicalgnostics (MG). As a non-statistical approach towards data uncertainty,MG enabled us to analyze the underlying phenomena that affect the value of the experimental heat capacity.
