| 摘 要： | 本文叙述并讨论了采用改进的Zeisel反应——气相色谱法测定聚醚中的甲氧基含量.实验表明:以磷酸-碘化钾为Zeisel反应试剂,以饱和水的苯溶剂为萃取剂,乙烯基甲基硅橡胶为固定液来分离碘代烷烃,可以获得较宽的检测范围及良好的定量结果.标准偏差<0.5％,本方法还可适用于多种高聚物中C_1～C_4的烷氧基官能团分析.

| Abstract: | An improved Zeisel gas chromatographic technique has been developed for the determination of the methoxy group in polyether. Phosphoric acid-potassium iodide was used as reaction agent to cleave the alkoxyl group and a solution of water-saturated benzene as an extraction agent to extract the corresponding iodoparaffins. Stationary phase is UCW 98 on 60/80 mesh chromosorb WMP. Standard deviation of this method is<0. 15% |
