摘　　要：本文建立了一种石油裂解油品中二烯烃的高效液相色谱分析方法,该方法使用Ag/Si固定相成功地分离和定量分析了热裂解石脑油样品中的二烯烃。首先,使用己烷流动相完成分离,给出了模型化合物的分离数据以及响应因子,得到了11种模型化合物的分析结果;然后,对4个代表样本进行定量研究。结果表明,该方法成功地定量了汽油和裂解石脑油样品中的二烯烃含量。A high performance liquid chromatography(HPLC)method for the determination of diolefin in petroleum cracking oil products was developed.Ag/Si stationary phase was used to successfully separate and quantify diolefin in naphtha samples.First,the separation was accomplished using a haxane mobile phase,and the separation data and response factors of model compounds were given to obtain the analysis results of 11 model compounds.Then four representative samples were quantified.The results showed that the method was successful in quantifying diolefin content in gasoline and cracked naphtha samples.
