英文摘要the heat capacities of chrysanthemic acid in the temperature range from 80 to 400 k were measured with a precise automatic adiabatic calorimeter. the chrysanthemic acid sample was prepared with the purity of 0.9855 mole fraction. a solid-liquid fusion phase transition was observed in the experimental temperature range. the melting point, t-m, enthalpy and entropy of fusion, delta(fus)h(m), delta(fus)s(m), were determined to be 390.741 +/- 0.002 k, 14.51 +/- 0.13 kj mol(-1), 37.13 +/- 0.34 j mol(-1) k-1, respectively. the thermodynamic functions of chrysanthemic acid, h-(t)-h-(298.15), s-(t)-s-(298.15) and g((t))-g((298.15)) were reported with a temperature interval of 5 k. the tg analysis under the heating rate of 10 k min(-1) confirmed that the thermal decomposition of the sample starts at ca. 410 k and terminates at ca. 471 k. the maximum decomposition rate was obtained at 466 k. the purity of the sample was determined by a fractional melting method.
