| 中文摘要 | the thermal stability and the solid solid phase transitions in ills compounds with n = 7-12 have been studied by dsc and tg methods. comparision with cnzn compounds want made. the nature of three phases of cncu has been discussed in terms of infrared spectroscopy and the assignment of the phase transitions has been given. the thermal stability of cncu is lower than that of cnzn and presents an obvious odd even effect. all of these compounds exhibit two solid solid phase transitions in the temperature range of 248-337 k. the peak tempe nature of phase transitions changes regularly. the peak temperature or the main phase transition increases with the chain length. the total transition enthalpies and entropies increase with increasing chain length. when n <= 9, the high temperature phase exists in a partial disorder state. when n >= 10, the high temperature phase exists in a conformational disorder state. the main phase transition and the phase transition at 307.7 k of cncu may mainly are from the change of the packing structure and the change of the partial conformational order-disorder of alkyl chain, respectively. |
