摘要
汽油中的共轭二烯烃是一种不安定成分,准确、迅速测定其含量,对研究油品质量及炼油工艺都有重要的意义。测定共轭二烯烃的方法早有报道,多用马来酸酐与共轭二烯发生定量反应,未反应的马来酸酐水解成马来酸。
This paper deals with the determination of conjugate define in cracked gasoline by capillary gas chromatography.The macropwrous silicagel impregnated with maleic anhydride was used as reactant of pre-column connected;with the capillary column.The influence of the method and degree of acidification on the reaction efficiency of conjugate olefine and other hydrocarbons was inspected The results show that the reaction efficiency of conjugate olefine is more than 98% using reactant treated with phosphoric acid.The precision and accuracy of this method are good.
