【摘要】 在填充柱气相色谱法的基础上，使用１２ｍ×０．２２ｍｍｉ．ｄ．的ＳＥ－３０短毛细管柱（ＷＣＯＴ），分析了乙烯生产副产物——未加氢裂解汽油（５５℃～２２０℃馏分）中共轭二烯烃的含量，分析一次需２２ｍｉｎ，内标物正十六烷得到了很好的分离。更多还原

【Abstract】 This paper is based on the packed column gas chromatography. By using a short capillary column (12m×0.22mmi.d.) coated with SE 30,the content of conjugated dienes in cracked gasoline (by product of ethene production without hydrogenation, with a boiling range of 55 220℃) could be determined. The analysis time of chromatography was 22min. A satisfactory separation of internal standard n Co16 with other components was obtained.更多还原
