Carboxylic acids produced from aliphatic constituents in coals after oxidation with RuO_4 were analyzed by ion chromatography and GC-MS. Results of such analyses suggest that metyl group is major substituent to aromatic ring, which amount is independent of coal rank. It is also suggested that amounts of ethyl group and dimethylen bridge increase for coals with lower rank. Maximum amount of phthalic ester was observed for coals with 80〜83wt%C, indicating that coals with such rank preferentially consisted of naphthalene nucleus.
