Distribution of Alkylene Bridge Bonds in Shenfu Coal

Abstract:

To understand the distribution of the alkylene bridge bonds which connect aromatic moieties and utilize coal effectively, Shenfu coal (SFC), its solvent extraction fractions and carbon disulfide (CS₂)/tetrahydrofuran (THF) inextractable matter (R_E) were subject to ruthenium ion-catalyzed oxidation (RICO). The results suggest that the carbon number of the alkylene bridge bonds range from C₀ to C₃₀ and that dominant alkylene linkage are C₂ and C₃ in SFC, a,w-diarylalkanes are soluble in a CS₂/THF mixed solvent, whereas highly condensed aromatic species in SFC show poor solubility in the CS₂/THF mixed solvent.
