Ruthenium tetroxide selectively oxidizes activated aromatic compounds under mild conditions to form aliphatic and benzene carboxylic acids. Macerals separated by density gradient centrifugation from a high volatile bituminous coal were oxidized by ruthenium tetroxide. The major aliphatic and aromatic acids produced were identified by gas chromatography - mass spectrometry. The differences in the yields and types of acids produced from the three maceral groups are discussed. The series of straight chain dicarboxylic acids obtained from exinite provide evidence of polymethylene chains which are not present in vitrinite nor inertinite. All three groups of macerals produce significant quantities of benzne polycarboxylic acids which are oxidation products of polyaromatic structures. Exinite and vitrinite produce similar quantities of these substances while inertinite produce large amounts of these acids. 27 refs., 7 figs., 4 tabs.
