| 英文摘要 | the low-temperature heat capacities of 2-chloro-5-trichloromethylpyridine were measured with a high-precision automated adiabatic calorimeter in the temperature range from 80 k to 345 k. a solid-liquid phase transition was observed from 318.57 k to 327.44 k with peak temperature 324.67 k; the molar enthalpy and entropy of phase transition, deltah(m) and deltas(m), were determined to be 14.50 +/-0.02 kj mol(-1) and 44.66 +/- 0.07 kj k-1 mol(-1), respectively. the thermal stability was investigated through thermogravimetric analysis (tg). the tg and dtg results reveal that 2-chloro-5-trichloromethylpyridine starts to lose mass at 332 k due to evaporation and completely changes into vapour at 483 k under the present experimental conditions. |
