色谱法测定醚化汽油中含氧化合物研究

Study on the Determination of Oxides in Etherified Gasoline by Chromatography

采用两种不同极性的弹性石英毛细管柱分析了 75℃以前催化裂化汽油及其醚化后汽油 ,测定了醚化汽油中单烃组成及含氧化物的含量 ,计算了单烯烃转化率并与红外数据进行了比较 。

Two kinds of different elastic quartz capillary column with the OV-1,PEG being the stationary phase were used to analyze the light catalytic cracking gasoline and etherified gasoline below 75℃. The composition of the single olefine and the oxygen compounds were determined.The conversion rate of the single olefine was calculated.The data determined by chromatography were compared with the data determined by IR.On the basis of the results the selection and the improvement of processing conditions and catalysts,the reaetion mechanism of etherification should be studied systematically.
