摘　　要：采用毛细管胶束电动色谱和气相色谱相结合的方法分析对二甲苯高温液相氧化过程的反应物、中间物和最终产物,在8min内定量分析出对二甲苯、对甲基苯甲醇、对甲基苯甲醛、对羧基苯甲醛、对甲基苯甲酸和对苯二甲酸等6个组分。该法分析速度快、操作简便、具有一定的准确度、。The micellar electrokinetic capillary chromatography(MECC) combined with gas chromatography(GC)were used to determine the reactants,intermediates and end-products of liquid phase oxidation of p - xylene to terephthalic acid at high temperature. p -Xylene(PX)?4-methylbenzyl alcohol (TALC)? p - tolualdehyde (TALD)?4-carboxybenzaldehyde (4-CBA)? p -toluic acid(PT) and terephthalic acid(TA) were analyzed quantitatively within 8 minutes.The method was rapid,convenient and accurate.
