摘要
本文报道了六种二苯并型冠醚化合物相变热行为和相变热力学参数,并讨论了这些化合物的熔点和熔化焓与它们的分子结构之间的相关性.
The phase transitions of six kinds dibenzo-type crown ethers (I-VI) were studied by differen- tial scanning calorimetry. The thermograms and therfhodynamic parameters of phase transitions of these compounds were obtained. There is a good correlation between the melting point and heat of fu- sion for these compounds and their molecular structures.
