| 摘 要： | 采用乙二胺(C2H8N2)为萃取剂,分别添加FeS2、MgCl2,MgCl2-AlCl3 3种催化剂对七台河煤进行索氏萃取,对萃取物采用气相色谱/质谱联用技术定性分析,探究了不同的催化剂对七台河煤萃取效果的影响。实验结果表明,催化剂有助于提高萃取率,增加萃取出的化合物的种类。MS分析证明,不同的催化剂可以抽提出不同的化学结构的物质,采用Cl盐作催化剂有利于含氧化合物的抽提,而FeS2有助于提高含芳环物质的抽提率,特别是对蒽系物的萃取效果良好。由试验结果推断,在煤萃取的溶剂体系里加入铁系催化剂、硫化物、卤族元素的可溶盐以及Lewis酸都可大大提高萃取效率。

| Abstract: | The effect of different catalyst for extracts of Qitaihe coal was investigated by methods of solvent extraction with C2H8N2 and GC /MS.Teh experimentation results show that catalysts can enhance the extraction rate and augment kinds of compounds of solvent extraction.Mass spectrometer analysis testified different catalysts can extract compounds with different structure,for instance,Cl-conduced to extraction of oxo-compounds and FeS2 conduced to increase ex-traction rate of aromatic hydrocarbons,especially f... |
