Ruthenium ion-catalyzed oxidation (RICO) was applied to investigate the structural details of Geting coal (GTC). A homologous series of straight- and branched-chain monocarboxylic acids were detected in the oxidation products, dominated by C4-C6 acids. Large amounts of aliphatic dicarboxylic acids ranging from C4 to C6 were also resolved, confirming the presence of the presence of methylene linkage. Whatever, the high recovery of benzene polycarboxylic acids indicates that GTC contains great quantity of polycyclic aromatic compounds.
