一种快速测定PAE树脂溶液中3-氯-1,2-丙二醇含量的方法
摘要：
本发明属于制浆造纸化学助剂检测技术领域，公开了一种快速测定PAE树脂溶液中3-氯-1,2-丙二醇含量的方法。所述方法为：将待测PAE树脂溶液稀释后依次加入高碘酸钠氧化和硼氢化钠还原，然后进行顶空气相色谱检测，记录甲醇的气相色谱信号值，将所得气相色谱信号值代入预先绘制的标准曲线中，得到PAE树脂溶液样品中MCPD含量。本发明的方法不需要配制有毒的有机溶液及复杂的溶剂抽提和衍生化处理，操作简单方便，效率高，实验结果客观准确，具有良好的应用前景。
摘要（英）：

The invention belongs to the technical field of detection of pulping and papermaking chemical assistants, and discloses a method for rapidly determining the content of 3-chloro-1,2-propylene glycol ina PAE resin solution. The method comprises the following steps: diluting a PAE resin solution to be measured, sequentially adding sodium periodate for oxidation and sodium borohydride for reduction,performing head-space gas chromatography detection, recording the gas chromatography signal value of methanol, and substituting the obtained gas chromatography signal value into a pre-drafted standardcurve to obtain the content of the MCPD in the PAE resin solution sample. The method has the advantages of no preparation of toxic organic solution, no complex solvent extraction or derivatization treatment, simplicity and easiness in operation, high efficiency, objective and accurate experiment result, and good application prospect.
