二氧化碳与甲醇直接合成碳酸二甲酯的气相色谱分析

Gas Chromatographic Analysis of Dimethyl Carbonate Produced by Carbon Dioxide and Methanol Synthesis

以GDX-203有机单体为固定相,用气相色谱法定性定量分析二氧化碳和甲醇直接合成碳酸二甲酯产物中甲醇和碳酸二甲酯;采用对照法定性、内标法进行定量分析,并对此法的准确性和精密度进行了考察。研究结果表明,该法定性、定量的结果均符合分析结果要求,具有实用价值。

With locking phase used by GDX - 203 organic monomer, a gas chromatographic method used in qualitative analysis and quantitative determination of the reactive product of dimethyl carbonate by carbon dioxide and methanol synthesis. Counter point was qualitative a-nalysis,and internal standard method was used in quantitative determination. The degree of precision and accuracy for each component in this method were examined. The experiment results showed it met the requirement of analytic result and had useful value.
