摘要
该文介绍了用高压液相色谱对族组分中的饱和烃、单环芳烃、二环芳烃及三环以上芳烃的精细分离方法。用二级活度的氧化铝除去非烃和沥青质,用正己烷和二氯甲烷依次淋洗出(硅胶)色谱柱上的饱和烃、单环芳烃、二环芳烃及三环以上芳烃。该方法同国外方法相比具有快速、节省试剂的优点,色质谱图显示各组分有较高的分离度。
Abstract
A method to finely separate saturated hydrocarbon and aromatic hydrocarbon by high performance liquid chromatography(HPLC)was introduced.The oil or bitumen samples were pre prepared by being put in a alumina column,saturated hydrocarbon and aromatic hydrocarbon were eluted together from the column using 90:10 of hexane:ether.After concentrated,the saturated hydrocarbon and aromatic hydrocarbon were ready for further separation by HPLC with the eluent hexane and dichloromethane.The fraction of saturates,monoaromatics,diaromatics and triaromatics would be collected under the control of UV detector and fraction collector.Compared with the method from abroad,the advantages of our method are visible:reagent and time saving.
