| 英文摘要 | the molar heat capacities of the room temperature ionic liquid 1-ethyl-3-methytimidazolium ethyl sulfate (emies) were measured by an adiabatic calorimeter in temperature range from 78 to 390 k. the dependence of the molar heat capacity on temperature was given as a function of the reduced temperature x by polynomial equations, c-p,c-m (j k-1 mol(-1)) = 178.6 + 50.28x + 2.886x(2) - 1.362x(3) + 0.6616x(4) + 7.155x(5) [x= (t - 132.5)/54.5] for the solid phase (78-187 k) and c-p,c-m (j k-1 mol(-1)) = 376.2 + 25.94x - 3.397x(2) - 0.6407x(3) + 0.8091 x-4 + 0.9869x(5) [x= (t - 292.5)/97.5] for the liquid phase (195-390 ), respectively. according to the polynomial equations and thermodynamic relationship, the values of thermodynamic function of the emies relative to 298.15 k were calculated in temperature range from 80 to 390 k with an interval of 5 k. the glass translation of emies was observed at 192.85 k. using oxygen-bomb combustion calorimeter, the molar enthalpy of combustion of emies was determined to be delta h-c(m)o -5152.6 +/- kj mol(-1). the standard molar enthalpy of formation of emies was evaluated to be delta(f) h-m(o) = -79.13 +/- 0.15 kj mol(-1) at t = 298.150 +/- 0.001 k.
