An investigation of the structure of asphaltene obtained from a G/sub 6/ gas coal is reported. Using a system based on extraction, liquid and thin-layer chromatography, 59 narrow-band fractions were separated accounting for more than 97% of the mass of initial asphaltenes. The structure of the asphaltenes was interpreted on the basis of cryoscopy, elemental and functional analysis, IR and UV spectroscopy and chromatography-mass spectrometry. The compounds contain aromatic, naphthenic and heterocyclic rings, substituted by phenolic, quinoid, methoxylic, ketone, alicyclic alcohol and short alkyl groups.
