ABSTRACT
In the framework of the IUPAC Project entitled Thermodynamics of ionic liquids, ionic liquid mixtures, and the development of standardized systems , 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide, [C6mim][NTf2], was selected as the standard ionic liquid on which to perform round-robin measurements on a series of selected properties. In this work, the pressure, density, temperature (p, F, T) surface was determined in the temperature range (293 to 338) K and up to a nominal pressure of 65 MPa. The isothermal compressibility and isobaric expansion coefficients were calculated from the (p, rho, T) data.
