| 英文摘要 | the molar heat capacities of the room temperature ionic liquid 1-butyl-3-methylimidazolium hexafluoroborate (bmipf6) weremeasured by an adiabatic calorimeter in temperature range from 80 to 390 k. the dependence of the molar heat capacity on temperature is given as a function of the reduced temperature (x) by polynomial equations, cp, m (j k-1 mol(-1)) = 204.75 + 81.421x-23.828 x-2 + 12.044x(3) + 2.5442x(4) [x = (t - 132.5)/52.5] for the solid phase (80-185 k), c-p,c-m (j k-1 mol(-1)) = 368.99 + 2.4199x + 1.0027x(2) + 0.43395x(3) [x = (t -230)/35] for the glass state (195 - 265 k), and c-p,c-m (j k-1 mol(-1)) = 415.01 + 21.992x - 0.24656x(2) + 0.57770x(3) [x = (t - 337.5)/52.5] for the liquid phase (285-390 k), respectively. according to the polynomial equations and thermodynamic relationship, the values of thermodynamic function of the bmipf6 relative to 298.15 k were calculated in temperature range from 80 to 390 k with an interval of 5 k. the glass transition of bmipf6 was measured to be 190.41 k, the enthalpy and entropy of the glass transition were determined to be delta h-g = 2.853 kj mol(-1) and delta s-g = 14.98 j k-1 mol(-1), respectively. the results showed that the milting point of the bmipf6 is 281.83 k, the enthalpy and entropy of phase transition were calculated to be delta(hm) = 20.67 kj mol(-1) and delta(sm) = 73.34 j k-1 mol(-1). |
