摘要

作者对超临界CO2萃取岩石中的烃类物作了一系列的实验,并与氯仿抽提作了对比。萃取4小时,可将岩石中70%的饱和烃分离出来,同时萃取物中90%以上是饱和烃,无需再分离,即可直接进行色谱分析。

Abstract

A series of supercritical extraction experiments on rocks using CO2 were carried out.The result was compared with chloroform extraction.70% of saturated hydrocarbons in rocks could be extracted out in 4 hours,and more than 90% of the extracts composed of saturated hydrocarbons,which could be directly injected into chromatography without the need of precedings.
