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(upsilon),) for imidazolium-based ionic liquids (ILs), namely, 1-ethyl-3-methylimidazolium methylsulfate [C(2)mim][MeSO4], 1-ethyl-3-methylimidazolium ethylsulfate [C(2)mim][EtSO4], 1,3-diethylimidazolium bis(trifluoromethylsulfonyl)imide [C2mim][Tf2N], and 1-decyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [C(10)mim][Tf2N] in the pressure (0.10 < P/MPa < 35.00) and temperature (293.15 < T/K < 393.15) domains. It is shown that experimental densities are in good agreement with the predicted densities obtained by the Gardas and Coutinho method and the correlation using the Tait equation and Sanchez-Lacombe equation of state. |
