abstract |
In the present work, experimental density measurements are reported along with the derived thermodynamic properties, such as the isothermal compressibility (K-T), the isobaric expansivity (alpha(p)) and the thermal pressure coefficient (gamma(v)) for imidazolium-, pyridinium-, pyrrolidinium-, and piperidinium-based ionic liquids (ILs), namely, 1-ethyl-3-methylimidazolium trifluoromethanesulfonate [C(2)mim][CF3SO3], 3-methyl-1-propylpyridinium bis(trifluoromethylsulfonyl)imide [C(3)mpy][NTf2], 1-butly- 1-propylpyrrolidinium bis(trifluoromethylsulfonyl)imide [C(3)mpyr][NTf2],1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide [C(4)mpyr][NTf2], and 1-methyl-1-propylpiperidinium bis(trifluorornethylsulfonyl)imide [C(3)mpip][NTf2] in the pressure (0.10 < P/MPa < 35.00) and temperature (293.15 < T/K < 393.15) domains. These ILs were chosen to provide an understanding of the influence of the cation and anion on the properties under study. Experimental densities are correlated with the Tait equation with an average absolute relative deviation (AARD) better than 0.02 %. It is shown that experimental densities are in good agreement with the densities obtained by the predictive method previously proposed by us. |
