| 摘 要： | 以GDX-102不锈钢填充柱,热导检测器,采用内标法对由CO2、CH3OH及环氧丙烷（PO）合成碳酸二甲酯（DMC）的主要物质进行了气相色谱的定量分析。探索了分析的最佳条件,同时以苯和正戊醇为内标物对这些物质的相对校正因子进行了计算,由回收率对校正因子进行了验证,结果表明,本方法对CH3OH、PO、DMC的分离效果较好,校正因子较为准确,具有潜在的应用价值。

| Abstract: | A gas chromatographic method for the one-pot synthesized dimethy carbonate(DMC) from CO2,CH3OH and epoxy alkyl(PO) with the GDX-102 thermal conductivity detector.Benzene and amylcohol was used as an internal standard.The separating column,internal standard and carrier gas determination were examined.The correction factors were calculated and it were validated by relatively standard deviation(RSD).The method is accurate and precision.It was applied to determine a practical sample with satisfaction. |
