摘　　要：研究了香豆胶原粉、阳离子香豆胶的红外光谱归属,并测定了它们的热失重及相应热效应峰值的红外光谱(TG-IR)。根据不同温度下阳离子香豆胶光谱基团的吸收峰变化和热失重-红外光谱的分析,推断该样品可能的热解过程。The title complexes shown as cationic fenugreek gum were prepared. The thermal decomposition process of fenugreek gum and cationic fenugreek gum was studied quantitativdy by means of thermogravimetric analysis and infrared spectroscopic measurement of samples after heating at different temperatures. Additionally, according to the fact that the absorbance peak changes and the analysis of TG-IR of cationic fenugreek gum at different temperatures, it can be drawn that the thermal decomposition of the cationic fenugreek gum might lead to a possible thermal-cracking process.
