Paper Title:
Analysis of Soluble Fraction with Carbon Disulfide/tetrahydrofuran of Erdos Coal by FTIR and GC/MS
  Abstract

A subbitumious coal from Erdos, Inner Mongolia, China, was extracted with isometric carbon disulfide/tetrahydrofuran (CS2/THF) mixed solvent. The components and structure features of CS2/THF soluble factions were analyzed by FTIR and GC/MS. The results show that the total extract yield was 6.6% after five extractions with fresh mixed solvent. And the mass fraction of the first extract was biggest which the 68% amount of the total extracts was. The FTIR spectra of the extracts had abundance functional group information, which can fully indicate that the extracts contain aliphatic compounds, aromatic compounds and heteroatom-containing compounds. Only the first extract can be detected by GC/MS among the five extracts and seven compounds were detected by GC/MS clearly and they are aromatic compounds, in which the three larger relative abundance compounds are retene, 7-butyl-1-hexylnaphthalene and 7-isopropyl-1,1-dimethyl-1,2,3,4-tetrahydro- phenanthrene.
