“…The knowledge of the thermophysical properties of pure ILs and their solutions, such as density, viscosity, and speed of sound, is fundamental in the design of processes and new products based on these chemical species . Moreover, density data are very important in the chemical process industry, especially those involving mass flow and heat transfer . Finally, experimental data of the speed of sound are useful in developing equations of state.…”

In this study, measurements regarding the density and speed of sound for binary liquid mixtures of the 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF6]) ionic liquid (+ methanol, or + acetonitrile, or + tetrahydrofuran, or + formamide, or + N,N-dimethylformamide, or + dimethylsulfoxide) were carried out as a function of the composition at temperatures between 288.15 and 313.15 K and atmospheric pressure. Experimental results allowed us to calculate the excess molar volume, , and excess isentropic compressibility, , which were fit to a Myers–Scott-type polynomial. The results for the studied systems suggest that structural effects and chemical interactions must predominate over other possible effects, except for the system containing formamide in which physical effects may also be more important.

The present paper contains data on the density (ρ), sound velocity (u), and specific heat capacity cp of the mixture of N,N-dimethylformamide + 1-butanol (DMF + BuOH) determined in the entire concentration range of solution and in the temperature range (293.15–318.15) K. The analysis of thermodynamic functions such as isobaric molar expansion, isentropic and isothermal molar compression, isobaric and isochoric molar heat capacity, as well as their excess functions (Ep,mE,KS,mE,KT,mE,Cp, mE,CV, mE) and also VmE was undertaken. The analysis of changes in the physicochemical quantities was based on consideration of the system in terms of intermolecular interactions and resulting changes in the mixture structure. The results available in the literature were confusing during the analysis and became the reason for our decision to thoroughly examine the system. What is more, for a system whose components are widely used, there is very scarce information in the literature regarding the heat capacity of the tested mixture, which was also achieved and presented in this publication. The conclusions drawn from so many data points allow us to approximate and understand the changes that occur in the structure of the system due to the repeatability and consistency of the obtained results.
