| 摘 要： | 用红外光谱表征了松香与顺丁烯二酸酐加成物及其溴化产物的分子结构,并与松香、松香溴化物进行了对比。利用综合热分析仪研究了松香、松香溴化物、顺丁烯二酸酐加成物及其溴化产物的热稳定性。结果表明松香和其加成物都容易溴化,溴化后由于生成弱的C-Br键而使其热稳定性下降。

| Abstract: | Addition reaction could take place between rosin and maleic anhydride. The rosin maleic adduct also could be bromized by liquid bromine. The molecular structures of rosin maleic adduct and its bromide were characterized by comparison with rosin and its bromide using their IR spectra. The thermal stabilities of rosin, rosin bromide, rosin maleic adduct and its bromide were studied by comprehensive thermal analyzer. The results showed that rosin and its adduct were easy to form bromides, and the thermal stabilities of bromides was decreased because of formation of weak C-Br bond. |
