“…That is why [C n mim]Br together with [C n mim]Cl represent a potential source of numerous ILs, and the study of their thermodynamic properties is of great importance. Thermodynamic parameters such as heat capacities, enthalpies of phase transitions, and surface tensions for a series of pure 1-alkyl-3-methylimidazolium bromide ILs have been reported at various temperatures [10][11][12][13][14].…”

Density and speed-of-sound data for 1-propyl-3-methylimidazolium bromide ([C 3 mim][Br]) + acetonitrile (MeCN), [C 3 mim][Br] + dimethylformamide (DMF), and [C 3 mim][Br] + dimethylsulfoxide (DMSO) binary mixtures in the dilute concentration region are reported at T = (288.15 to 308.15) K. From these data, apparent molar volume, isentropic compressibility, excess molar volume, and isentropic compressibility deviation values have been calculated. Negative deviations from the ideal behavior of both molar volume and isentropic compressibility have been observed for all systems investigated in this study. It has been found that deviations from ideal behavior for the [C 3 mim][Br] + MeCN system are larger than those for the [C 3 mim][Br] + DMF system which, in turn, are larger than those for the [C 3 mim][Br] + DMSO system. The results have been interpreted in terms of ion-dipole interactions and structural factors of the ionic liquid and investigated organic solvents.

“…The Br anion shows a stronger interface with TFE than the BF4 anion. This means that the required temperature for regeneration will be smaller and the vapor pressure lines will be steeper [23]. Novel working fluids for an absorption heat pump have been proposed by investigating ionic liquids and fluoroalcohol.…”

The cycle performance of refrigeration cycles depends not only on their configuration, but also on thermodynamic properties of working pairs regularly composed of refrigerant and absorbent. The commonly used working pairs in absorption cycles are aqueous solutions of either lithium bromide water or ammonia water. However, corrosion, crystallization, high working pressure, and toxicity are their major disadvantages in industrial applications. Therefore, seeking more advantageous working pairs with good thermal stability, with minimum corrosion, and without crystallization has become the research focus in the past two decades. Ionic liquids (ILs) are room-temperature melting salts that can remain in the liquid state at near or below room temperature. ILs have attracted considerable attention due to their unique properties, such as negligible vapor pressure, nonflammability, thermal stability, good solubility, low melting points, and staying in the liquid state over a wide temperature range from room temperature to about 300 ∘ C. The previously mentioned highly favorable properties of ILs motivated us for carrying out the present research and reviewing the available ILs found in the literature as the working fluids of absorption cycles. Absorption cycles contain absorption heat pumps, absorption chillers, and absorption transformers.
