乙醇脱水制乙醚产物的气相色谱分析

The Gas Chromatographic Analysis of the Product of the Alcohol Dewaterling into Ethyl Ether

报导乙醇脱水制乙醚产物气相色谱定量分析方法的研究结果。实验表明，以GDX-103为固定相，环已烷为溶剂，乙酸乙酯为内标物，采用内标标准曲线法，在合适的色谱操作条件下，可以得到准确的分析结果，同时具有样品不必进行前处理，操作简便，快速的特点。可以作为研究过程中间产物分析的方法使用。

The research of the gas chromatograpnic quantitative analytical method for the product from the experiment in which ether was prepared from dehydrated ethanol was reported in this paper.The experimental confusions showed that with GDX-103 used as the stationary phase, cyclohexans as the solvent and ethyl acetate as the interior standard, the accurate analytical results could be attained by the interiostandard curve under the suitable chromatographis conditions. This method made the experiment rapid and easy to operate without sample pretreatment so that it could be used to analyse the intermediate product during the experiments.
