Summary
Ionic liquids have proved to be excellent heat transfer fluids and alternatives to common HTF’s used in industry for heat exchangers and other heat transfer equipment. However, its industrial utilization depends on the cost/kg of its production, to be competitive for industrial applications with biphenyl and diphenyl oxide, alkylated aromatics and dimethyl polysiloxane oils, which degrade above 200ºC and possess some environmental problems. The efficiency of a heat transfer fluid depends on the fundamental thermophysical properties influencing convective heat transfer (density, heat capacity, thermal conductivity, and viscosity), as these properties are necessary to calculate the heat transfer coefficients for different heat exchanger geometries.\\nIn part 1, the thermophysical properties of pure 1-ethyl-3-methylimidazolium methanesulfonate [C2mim][CH3SO3] (CAS no. 145022-45-3), (ECOENG™ 110), produced by BASF, under the trade name of Basionics® ST35, with an assay ≥ 97% with ≤ 0.5% water and ≤ 2% chloride (Cl-), were presented, for temperatures slightly below room temperature and up to 355 K. \\nIn this paper we report the thermophysical properties of mixtures of [C2mim][CH3SO3] with water, in the whole concentration range, at P = 0.1 MPa. The properties measured were density and speed of sound (293.15 < T/K < 343.15), viscosity, electrical, thermal conductivity and refractive index (293.15 < T/K < 353.15), and infinite dilution diffusion coefficient of the ionic liquid in water (298.15 K).\\nProperties for the mixture like the isobaric expansion coefficient, the isentropic compressibility, apparent molar volumes, apparent molar isentropic compressions, and the thermodynamic excess properties, like excess molar volume, excess molar isobaric expansion and isentropic compression, excess viscosity, molar refraction, and infinite dilution diffusion coefficients of the cation, the anion and other common anions in ionic liquids were obtained, within this temperature range. The validity of the Walden relation for this ionic liquid was also determined. This amount of experimental information, in addition to recent molecular simulation studies available in the literature permit a clear picture of the structure of these binary mixtures, the influence of composition and temperature, paving the way to a technological discussion of the possible application of these mixtures as new heat transfer fluids or battery electrolytes.
