摘要

Shenfu coal was extracted with CS2,n-hexane,benzene sequentially.The extracts were analyzed with GC/MS.It is presented that group seperation of soluble organic compounds in the coal can be achieved by fractionated extraction using different solvents.Main components in CS2 soluble fraction from Shenfu coal are alkyl-substituted arenes.Aliphatic hydrocarbons are overwhelmingly predominant in n-hexane-soluble fraction.Dito tricyclic aramatic hydrocarbons are identified in benzene-soluble fraction.The molecular structures detection of 2,4,6-trichlorobenzenamine and 3,3',4,4',5,5'-hexachloro-1,1'-biphenyl and 2-chiorocyclohexanol firstly provide information for existence form of chlorine in coal.
