对二甲苯液相氧化体系分析方法进展

The development of the analytical methods used in the system of p-xylene oxidation

综述了运用于PX液相氧化体系反应物、产物及杂质的分析方法,主要有极谱法、气相色谱法、液相色谱法、毛细管电泳法、毛细管胶束电动色谱法以及气相色谱和液相色谱相结合、气相色谱和毛细管胶束电动色谱相结合的方法,讨论了各种方法的适用范围和优缺点。

Several analytical methods used to analyze the reacant,products and impurities in the system of pxylene oxidation are generalized.They are by polarogram, using gas chromatography directly or divation before using gas chromatography,liquid chromatography,free solution capillary electrophoresis, micellar electrokinetic capillary chromatography,gas and liquid chromatography. gas chromatography and micellar electrokinetic capillary chromatography.Their practicabilities,merits and drawbacks are discussed.
