One key application is their use as absorbents in absorption refrigeration cycles, replacing water + LIBr and water + ammonia systems. As a possible mixture, the system [Bmpyr][dca] + H2O was studied, as the available data are scarce. Measurements of density, speed of sound, viscosity, and surface tension of [Bmpyr][dca] + H2O were made for seven molar compositions between 288.15 K and 333.15 K. The uncertainty of the density values is 0.07 kg·m–3, while that of the speed of sound was found to be 0.3 m·s–1. Viscosity measurements have an uncertainty of 1.4 %, while the surface tension values have an uncertainty lower than ±0.6 mN·m–1. All the measurement were measured at atmospheric pressure and are reported to 0.1 MPa ± 1 kPa. From density data, isobaric molar expansions were calculated and from combined density and speed of sound data, isentropic molar compressions were also obtained. Finally, excess molar vo...

Data obtained with an absolute relative uncertainty of Ur (η) = 0.02 was compared with available literature data for all ionic liquids, except for [Aliquat][N(CN)2], data herein presented for the first time. Both the Vogel-Tammann-Fulcher and IUPAC/IAPWS equations were applied to correlate the measured viscosity data as a function of temperature, the latter being more accurate. Values of η (298.15 K) are recommended for each ionic liquid studied. The viscosities of the different ionic liquids are discussed, considering their chemical structure differences.
