摘　　要：对五种苯并硫冠醚化合物（Ⅰ～Ⅴ）进行了ＤＳＣ研究，提供了它们在相变时的ＤＳＣ热谱图和热力学参数．实验结果表明，化合物Ⅰ、Ⅳ、Ⅴ在相变过程中呈现熔化单峰，化合物Ⅱ、Ⅲ呈现熔化双峰，其熔点、熔化热与分子结构之间存在着一定的相关性．The phase transitions of five new benzothia(oxa)-crown ethers(Ⅰ～Ⅴ)were studied by differential scanning calorimetry(DSC).The thermograms and thermodynamic parameters of phase transitions of these compounds were obtained.A singlemelting peak was observed on the thermogram for the compounds Ⅰ、Ⅳ、Ⅴ, a multimelting peak was observed on the thermogram for the compounds Ⅱ、Ⅲ, there is a good correlation between the melting point and heat of fusion for these compounds and their molecular structures.
