文摘

Experimental densities, isobaric heat capacities, and enthalpies of fusion for one sample of 1-butyl-3-methylimidazolium hexafluorophosphate, [bmim][PF₆], and two samples of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, [bmim][NTf₂], are reported. Data were obtained at atmospheric pressure and, inthe case of the density and the heat capacity, within the temperature intervals (283.15 to 323.15) K and (278.15to 333.15) K for [bmim][PF₆] and [bmim][NTf₂], respectively. A critical analysis of the effect of impurities onthe measured thermodynamic properties is performed.
