Distillates of a coal-derived liquid have been separated into compound classes by HPLC. High-voltage GC/MS and low-voltage GC/MS technique have been employed to analyse the individual components and the hydroaromatic group type concentrations in the HPLC fractions.<BR>The result of the analyses shows that the coal-derived solvent contains hydrogen donor compound types (e.g., tetralin, hexahydroacenaphthylene, hydropyrene) and nonhydrogen-donor compound types (e. g., fluorene, acenaphthene, dibenzofuran).<BR>The proton donatable quality index (PDQI) has been calculated from the data of donatable naphthenic hydrogen contents in hydroaromatic species analysed by HPLC and GC/MS method. The PDQI values suggest that the monoaromatic compound class has high hydrogen donatability and the other compound class'es have low hydrogen donatability.<BR>The tendency obtained from HPLC and GC/MS method was in good agreement with that of the naphthenic hydrogen contents estimated by <SUP>1</SUP>H-nmr spectral method.
