摘　　要：本文研究了喷气燃料中悬浮物有机成分的分离和定性分析。先通过孔径0.025μm的微孔滤膜过滤分离出喷气燃料中的悬浮物,依次用正己烷和二氯甲烷提取悬浮物中的有机成分,再利用气相色谱/质谱联用技术对悬浮物的正己烷相溶液和二氯甲烷相溶液进行定性分析,共检测出了2,6-二叔丁基对甲酚、1,2-二氧芑-3-乙酸,6-十六烷基-3,6-二氢-6-甲氧基-甲基酯、5-甲基-5H-苯并[23-c]咔唑等47种成分,为研究悬浮物的形成机理提供了实验依据。The purpose of this study is to investigate the organic composition of suspended matters in jet fuels. Separation and qualitative analysis of the organic components of suspended matters are reported. After jet fuels are filtered by microporous filter membranes with 0. 025 μm pore size, the organic components of suspended matters are extracted with n-hexane and dichloromethane in turn. The qualitative analysis of the organic components is carried out using a gas chromatography-mass spectrometry. There are 47 kinds compounds detected,including butylated hydroxytoluene, 1,2-dioxin-3- acetic acid, 6-hexadecyl-3,6-dihydro-6-methoxy-, methyl ester, 5-methyl-5 H-naphtho[ 23-c] carbazole and so on. The analytical results are useful for the prediction the formation mechanism of suspended matters in jet fuels.
