“…Due to their superior properties (including wide liquid range, extremely low volatility and high thermal stability, etc), ILs were considered as good alternatives to traditional organic solvents in different applications, such as separation process [2], catalysis [3], or electrochemistry [4], and so on. In addition, ILs were also applied to the absorption refrigerant systems (ARS) as the absorbents to solve the problems of the traditional NH 3 /H 2 O or H 2 O/LiBr working pairs [5][6][7][8], for example the corrosion for NH 3 /H 2 O and easy crystallization for H 2 O/LiBr.…”

The working pairs composed of hydrofluoroolefins (HFOs) and ionic liquids (ILs) have exhibited promising potential in the absorption refrigeration systems (ARS). In order to exploit the possibility of 3, 3, 3-trifluoropropene/ILs as the pairs used in the ARS, the experimental determination on the solubility of 3,3,3-trifluoropropene in 1-hexyl-3-methyl-imidazolium trifluoromethanesulfonate ([hmim][TfO]) and 1-octyl-3-methyl-imidazolium trifluoromethanesulfonate ([omim][TfO]) ILs was conducted. The present measurements were carried out based on the isochoric saturation method at the temperature range from 303.15 K to 343.15 K. The experimental solubility data were correlated through the non-random two liquid (NRTL) model and Krichevsky-Kasarnovsky (K-K) model, respectively. In addition, the influence of the alkyl chain length for different ILs on the solubility of R1243zf and the dissolving capacities of different HFOs in [hmim][TfO] were compared. Furthermore, the Henry’s constants and mixing thermodynamic properties (enthalpy, entropy and Gibbs Energy) of R1243zf in [hmim][TfO] and [omim][TfO] were calculated and discussed.
