| 摘 要： | 喷气燃料中的不安定组分对燃料安定性影响很大,不安定组分主要集中在胶质化合物中,胶质化合物的存在会增加燃烧积炭,影响航空发动机的正常使用1-2]。不安定组分含量极少,必须通过一定条件的分离和富集才能进行分析和评价。本文采用中性氧化铝吸附和极性溶剂脱附的方法分离制备

| Abstract: | The jet fuel sample passed through a column packed with neutral alumina powder adsorbent,then the gum adsorbed on the adsorbent was washed out with acetic acid.The gum samples were detected by gas chromatography-mass spectrometry with capillary column and pyrolysis chromatography-mass spectrometry.The predominant components in gum are alkyl phenols and aryl esters. |
