摘要
采用气相色谱-质谱法分析了火箭煤油的组成。在选用的分析条件下,共检测出159个峰,鉴定了其中的131个峰,鉴定出的组分占火箭煤油总量的80.37%。分析发现,火箭煤油中有约一半是双环环烷烃,其次是单环环烷烃和异构烷烃,正构烷烃、含氧化合物、烯烃、三环环烷烃和芳烃含量较少。双环环烷烃以烷基萘烷、烷基螺[5.5]十一烷和环烷基环己烷为主,分别占双环环烷烃的49.04%、19.28%和16.64%。单环环烷烃主要是烷基环己烷和烷基环戊烷,分别占单环环烷烃的66.62%和31.10%。
Components in rocket kerosene were analyzed by gas chromatography-mass spectrometry.In the condition adopted,159 peaks were detected in total ion current chromatogram（TIC） of rocket kerosene,131 peaks among them were identified.The components identified account for 80.37% of total amount of rocket kerosene.It is found in rocket kerosene that,almost half of all components are bicyclo-paraffins,followed by monocyclo-paraffins and iso-alkanes,still by little n-alkanes,oxygen-containing compounds,alkenes,tricyclo-paraffins and aromatics.Most bicyclo-paraffins are alkyldecalins,alkylspiroundecanes,and naphthenic cyclohexanes,which respectively account for 49.04%,19.28% and 16.64% of bicyclo-paraffins.Monocyclo-paraffins are mostly alkylcyclohexanes and alkylcyclopentanes,which respectively account for 66.62% and 31.10% of monocyclo-paraffins.
