    Abstract
  • In order to find whether copper joins the organic compounds reaction,some soxhlet extractor experiments are done.The samples are Huangxian lignite,Shenshan lignite in Ordas basin,argillaceous limestone in Tarim baisn and lime mudstone in Qaidam Basin.They are divided into two series:A and B.In A series,copper is added for eliminating sulfur.And there is not copper with B series during extracting.The results show that copper can react with some organic compounds in extracted matter and form organo-metallic compounds.So it will greatly influence the results of sample pretreatment.After B series experiments,saturated hydrocarbon and sulfur are separated from extracted material as one fraction by co-lumn chromatography.Then we add copper into this fraction to eliminate sulfur.This method can reduce the influence of copper on the quantitative analysis of the organic matter.
