有机硅密封胶粘附性能的改善(精)

012%, 在65℃下反应2h , 苯酚/桐酯量比为7/3为最佳反应条件。在此条件下, 得率可达8317%。由液相色谱分析表明:桐酸甲酯

和苯酚以1∶1加成。本产物的合成, 将为提高桐油资源的利用价值、桐酸改性酚醛胺树脂的研究提供物质基础。

Abstract Adduction of methyl eleostearate with phenols were studied. The effects of prepara 2tion condition such as the types and usage of cata 2lyst ,reaction time , reaction temperature and molar ratio on the reaction were studied. HPL -MS indi 2cated that the main product was the adduct of 1

mol eleostearate and 1mol phenol. IR indicated that eleosterarate was adducted to the parasite of phenol.
