介绍了一种草酸二乙酯催化加氢制乙二醇液相产物的气相色谱分析法，色谱分析在ＧＣ－１０３型色谱仪上进行，用ＣＤＭＣ－１ＣＸ型色谱数据处理机计算，液相产物在内填５％ＦＦＡＰ／６０～８０目硅藻土８８０（ＡＷＤＭＣＳ）的不锈钢色谱柱上分离，用热导检测器检测，以２０ｍＬ／ｍｉｎ流速的氢气为载气，每个样品的分析时间约为１０ｍｉｎ。方法快速简便，数据较为精密准确。 A gas chromatographic method for the catalytic hydrogenation of diethyl oxalate to the liquid phase of ethylene glycol was introduced. The chromatographic analysis was performed on a GC-103 chromatograph. The chromatographic analysis was performed on a CDMC-1CX chromatographic data processor. The liquid phase product Separation was performed on a stainless steel column packed with 5% FFAP / 60-80 mesh diatomaceous earth 880 (AWDMCS), detected with a thermal conductivity detector, with hydrogen at a flow rate of 20 mL / min as the carrier gas, and the analysis time per sample was about For 10min. The method is quick and easy, the data is more precise and accurate.
