摘要：

在柱色谱柱中填充100～200目的硅胶,以二甲亚砜为洗脱剂,将F-T合成油产物分离为烃类及有机含氧化合物两部分。采用气相色谱-质谱(GC-MS)对有机含氧化合物部分进行了分析,共鉴定出有机含氧化合物139种,并对其出峰规律进行了总结。

Abstract:

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.
