摘要：
A systematic atomic group determination by high performance liquid chromatography (HPLC) and nuclear magnetic resonance (NMR) is proposed for the estimation of physical properties of hydrocarbons in a coal-derived liquid. HPLC has been used for the separation of hydrocarbons into compound classes according to the number of aromatic rings. The structural analyses of these compound classes were performed by using H-1 and C-13 NMR. The chemical structures of the compound classes are characterized by seven atomic groups. The numbers of these atomic groups in an average molecule for each fraction were calculated based on the results from this method. The physical properties of coal-derived liquids will be estimated from the chemical structure of the hydrocarbons by the method proposed here.
