摘　　要：为了监测吗啉甲基化法生成N-甲基吗啉反应的收率,本文应用气相色谱建立了一套用N-甲基吡咯烷酮作为内标物,程序升温测定N-甲基吗啉质量分数的方法。该方法主要依托于HP6890A气相色谱,其检测器为氢火焰离子检测器,载气为氮气,色谱柱为SE-54毛细管柱(规格50 m×0.53 mm×1.00μm)。通过回收率和重复性的测定,验证了该方法准确度和精密度均较高,能够准确测定混合液中N-甲基吗啉的含量。Aiming at the analysis of 4-methylmorpholine＇s content in mixed liquid with gas chromatography,internal standard method was established. Using the HP6890 A gas chromatography with flame ionization detector and SE-54 capillary column（50 m × 0. 53 mm × 1. 00 μm）,a practical temperature programmed method for determination of4-methylmorpholine content was built up. This method was proved with highly precision while detecting mass content of4-methylmorpholine in mixed liquid,by detection of GC recovery and repeatability.
