Lingwu coal was extracted with isometric carbon disulfide/N-methyl-2-pyrrolidinone(CS2/NMP) mixed solvent under ultrasonic irradiation.The extracts were sequentially eluted with n-hexane,benzene,chloroform and tetrahydrofuran(THF),affording fractions 1 to 4(F1 to F4),and each fraction was analyzed with GC/MS.The results show that saturated hydrocarbon are highly concentrated in the F1.Polynuclear aromatic hydrocarbon are the most abundant in the eluants with chloroform,and most components in the eluants with THF are oxygen-containing organic compounds.
