【摘要】 香兰素与盐酸肼经缩合得到香兰素腙,其结构经~1H-NMR、IR表征,并在静态空气气氛中用热重-差示扫描量热分析法对其进行热分析研究,结果表明,在209-330℃之间出现第一个失重阶段,失重36.09%,331-610℃之间出现了第二个失重阶段,失重64.44%,在整个DTG曲线上的最快失重速率点在310℃;在207℃出现强吸热峰。更多还原

【Abstract】 Vanillinhydrazone was synthesized by the condensation reaction of vanillin and hydrazine dihydrochloride,and its structure was identified by IR and ~1H-NMR.Further more,its thermal stability also was studied by TG-DTG and DSC methods in the static air atmosphere.The result indicated that a mass loss of 36.09%was discovered in the first stage with the temperature range of 209-330℃,and 64.44%in the second stage from 331 to 610℃.the fastest rate point of the mass loss was at 310℃in the DTG.The maximum peak at 207℃in DSC was observed by endothermic reaction.更多还原
