中文摘要	molar heat capacities (cp,m) of the ionic liquids (ils) n-alkylpyridinium hexafluorophosphate ([cnpy][pf6] n = 2, 3) were measured with a high-precision automated adiabatic calorimeter [1] in temperature range from 80 to 400 k. melting temperatures were observed at 374.278 ± 0.593 k for [c2py][pf6] and 370.956 ± 0.309 k for [c3py][pf6]. the enthalpy and entropy of the phase transition were also determined. two polynomial equations of molar heat capacity as a function of the temperature were fitted before and after the melting temperature for each ionic liquid. the thermodynamic functions (ht – h298.15) and (st – s298.15) were derived [2] from the molar heat capacity data in the temperature range of t = (80 to 400) k with an interval of 5 k.
