Abstract
Shenfu coal (SFC), its liquefaction residue (R<sub>L</sub>), and carbon disulfide (CS<sub>2</sub>)/tetrahydrofuran (THF)-inextractable matter (R<sub>E</sub>) were subject to ruthenium ion-catalyzed oxidation to understand the differences in structural features among the above three samples. The results suggest that SFC is rich in long-chain arylalkanes and α,ω-diarylalkanes (DAAs) with carbon number of methylene linkage from 2 to 4 and that long-chain arylalkanes and DAAs are reactive toward hydroliquefaction and soluble in a CS<sub>2</sub>/THF mixed solvent, whereas highly condensed aromatic species in SFC show poor solubility in the CS<sub>2</sub>/THF mixed solvent
