摘　　要：对所合成的香兰素对硝基苯腙在静态空气气氛中进行了热重-差示扫描量热分析。结果表明,在184～289℃之间出现第一个失重阶段,失重32.5%;290～650℃之间出现第二个失重阶段,失重27.0%,且整个DTG曲线上的最快失重速率点在236℃;而化合物分子的剩余部分在651℃开始炭化,炭的总量约占样品的35.5%;化合物在184℃以下热稳定性良好。The thermal stability of vanillin p-nitrophenylhydrazone was studied by TG-DTG and DSC methods in the static air atmosphere.The results indicated that a mass loss of 32.5% was discovered in the first stage with the temperature range of 184~289 ℃,and then a mass loss of 27.0% in the second stage with the temperature range of 290~650 ℃.The fastest rate point of the mass loss was at 236 ℃ in the DTG curve.The rest of the compound was carbonated at 651 ℃,for which amount of carbon was 35.5% of that of samples.The compound had good thermal stability below 184 ℃.
