摘要
采用自行研制的萃取系统对神府煤进行了石油醚溶剂萃取,并结合GC/MS技术对萃取物进行了定性和定量分析,讨论了萃取物的化学组成及其萃取过程.结果显示,神府煤石油醚萃取物的GC/MS可测组分主要由脂肪烃、芳烃及含氧杂原子化合物组成,其中含氧化合物相对含量达到72%;各次循环萃取量经历了从低到高、再从高到低的过程;各分子化合物在溶剂中的溶解析出规律有较大差异.
In this paper, Shenfu coal was extracted with the petroleum ether （PE） through a special equipment designed by ourselves, PE-soluble fractions were analyzed by GC/ MS and quantified by GC respectively. The results show that： fractions identified with GC/MS mainly consists of aliphatic hydrocarbons, aromatic hydrocarbons and heteroatom compounds among which the relative content of oxygen compounds is 72%; the yields of each circle extraction alter from low to high,then from high to low; the dissolution speed of each component is different in solvent.
