摘要：
In the present work the binary mixtures containing the ionic liquid N-hexylisoquinolinium thiocyanate, [HiQuin][SCN] and water was considered as a new working pair for absorption refrigeration. Experimental heat capacities and excess enthalpies of the binary mixtures were determined at different ionic liquid mole fractions over a wide range of temperature at ambient pressure. The influence of temperature and composition on measured properties was assessed and suitable equations were used to correlate the experimental data. (C) 2012 Elsevier Ltd. All rights reserved.
