Shenfu coal was extracted with CS2, n-hexane, benzene sequentially. The ex-tracts 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. Di-to 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-chlorocyclohexanol firstly provide information for existence form of chlorine in coal.
