摘　　要：裂解碳五原料经选择性加氢和甲醇醚化反应后,产物组中既有非极性的碳四、碳五烃类,又有极性的甲醇、甲基叔戊基醚和叔戊醇。使用单根毛细管柱很难将包含了17种沸点接近且结构、极性不同的单体烃组分有效分离,为此,实验中使用了一种能将极性柱与非极性柱特殊串联的方式,方便快捷的解决了碳五醚化后产物组成测定的难题。There are non-polar compounds such as carbon four,carbon five,and polar compounds such as methyl alcohol,methyl tert-amyl ether and tert-amyl alcohol in the product of carbon five raw materials after the selective hydrogenation and the methyl alcohol etherification response.It is difficult to separate them by using highly effective capillary column because of their close boiling point.We use an especial way which the polar column and the non-polar column are coupled,then the problem is solved.
