英文摘要 | the heat capacities of trans-(r)-3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylic acid in the temperature range from 78 to 389 k were measured with a precise automatic adiabatic calorimeter. the sample was prepared with the purity of 0.9874 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 344.75 +/- 0.02 k, 13.75 +/- 0.07 kj mol(-1), 39.88 +/- 0.21 j k(-1) mol(-1), respectively. the thermodynamic functions of the sample, 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 thermal decomposition of the sample was studied by tg analysis, the thermal decomposition starts at ca. 421 k and terminates at ca. 535 k, the maximum decomposition rate was obtained at 525 k. the order of reaction, pre-exponential factor and activation energy, are n=0.14, a=1.15 center dot 10(8) min(-1), e=66.27 kj mol(-1), respectively. |
