TG-DSC (in air) and TG-FTIR (in nitrogen) techniques. The compounds were also characterized by infrared spectroscopy. In addition, IR spectra were calculated and compared with the experimental data. In particular, the potential energy distribution analysis was performed to assign IR signals. The studied compounds are characterized by good thermal stability in oxidizing and inert atmospheres which is
本文通过TG-DSC(空气中)和TG-FTIR(氮气中)技术报道了六种吲哚衍生物的热稳定性和热降解。还通过红外光谱对化合物进行了表征。另外,计算红外光谱并将其与实验数据进行比较。特别地,进行势能分布分析以分配IR信号。所研究的化合物的特征是在氧化性和惰性气氛中具有良好的热稳定性,这对潜在的医学应用至关重要。空气中的热重测量表明,化合物的分解过程分为两个或三个主要阶段。化合物的热降解之前是熔融过程。样品的热解是一个一步的过程。加上在氮气中进行的分析,记录气相产物的FTIR光谱。在气态产物的FTIR光谱上,仅存在水,二氧化碳和碳氧化物分子的谱带。如果吲哚衍生物含有p -氯苄基的取代基在位置1,苯甲醚,的频带p -chlorotoluene和氯苯也出现。
