Liquid range temperature of ionic liquids as potential working fluids for absorption heat pumps
M Villanueva, JJ Parajó, PB Sánchez, J García… - The Journal of Chemical …, 2015 - Elsevier
The liquid range temperature of six ionic liquids (ILs) was determined in this work with the
aim to propose suitable absorbents for heat pump systems. The selected ILs have three
different cations, imidazolium, pyridinium and choline and each was combined with four
different anions [NTf 2]−,[OTf]−,[MeSO 3]− and [BETI]−. The lower limit, given by solid− liquid
transitions, was determined using differential scanning calorimetry (DSC). The upper limit is
given by the degradation temperature. This temperature is determined using …
