摘要
本文用统计热力学方法，在温度２００～１２００Ｋ范围内，计算了ＣＨＣｌ２＋＋ｅ→ＣＨＣｌ２，以及ＣＨＣｌ２翻转过程的热力学函数及速度常数。结果表明：ＣＨＣｌ２在高温下是稳定的，这与ＣＨ２Ｃｌ２进一步氯化时经历自由基历程的结论相吻合；最后讨论了标题物质的等容热容及随温度的变化。
The thermodynamic functions and the rate constants were calculated for CHCl+2→CHCl*2, and for inversion of CHCl*2 over the temperature range 200～1200K with standard statistical thermodynamic method. It was shown that CHCl*2 could exist stably at relatively high temperature, which is in good agreement with radical mechanism of chloration for CH2Cl2. Finally, the heat capacity for titled molecule and its temperature dependence were discussed.
