Analysis of Oxygenates from Fischer-Tropsch Synthesis Oil Using Column Liquid Chromatography and Gas Chromatography-Mass Spectrography
柱色谱分离、气相色谱-质谱法定性分析F-T合成油中的含氧化合物

A liquid chromatographic column filled with silica gel of 100-200 mesh was used to separate cold trap oil from Fischer-Tropsch synthesis with dimethylsulfoxide(DMSO) as eluent.With this pretreatment method,the cold trap oil was separated into two major classes,namely,hydrocarbons and oxygenates.Minor components were also enriched and determined,and small peaks adjacent to big peaks and tailings were also well solved.The oxygenates were then analyzed with gas chromatography-mass spectrometry(GC-MS),and 139 components were identified.
