| 英文摘要 | the molar heat capacities of the room temperature ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate ( bmibf4) were measured 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, c-p,c-m ( j k-1 mol(-1))= 195.55+ 47.230 x - 3.1533 x-2+ 4.0733 x-3+ 3.9126 x-4 [ x=( t - 125.5)/45.5] for the solid phase ( 80 similar to 171 k), and c-p,c-m ( j k-1 mol(-1))= 378.62+ 43.929 x+ 16.456 x-2 - 4.6684 x-3 - 5.5876 x-4 [ x=( t - 285.5)/ 104.5] for the liquid phase ( 181 similar to 390 k), respectively. according to the polynomial equations and thermodynamic relationship, the values of thermodynamic function of the bmibf4 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 bmibf4 was observed at 176.24 k. using oxygen-bomb combustion calorimeter, the molar enthalpy of combustion of bmibf4 was determined to be delta h-c(m)o= - 5335 +/- 17 kj mol(-1). the standard molar enthalpy of formation of bmibf4 was evaluated to be delta h-f(m)o= - 1221.8 +/- 4.0 kj mol(-1) at t= 298.150 +/- 0.001 k. |
